Description
Technical Field
The present invention relates to an isolation device design support device, an isolation device design support program, and an isolation device design support method.
The present application claims priority based on japanese patent application No. 2019-110592 filed in japan on 6/13 th year 2019 and japanese patent application No. 2019-110594 filed on 6/13 th year 2019, the contents of which are incorporated herein by reference.
Background
When an automobile manufacturer or an automobile component manufacturer determines specifications of components to be used in a commercially available automobile, the following tests are sometimes performed: a trial component is produced and assembled to a real vehicle, and the real vehicle is actually operated to collect various data.
In addition, such a test requires labor for producing a trial part and labor for actually operating an actual vehicle. Therefore, such labor is reduced by using a spring design system disclosed in patent document 1, for example.
The spring design system disclosed in patent document 1 includes a spring calculation unit, a spring characteristic database, and a server. The spring calculation unit calculates the spring of the coil spring based on the specification data of the coil spring, and outputs specification data (specification data) including the characteristic value of the coil spring obtained as a result of the calculation. The spring characteristic database judges whether or not the specification data including the obtained characteristic value of the coil spring is suitable for the required specification. The server determines whether the specification data is suitable as the data of the coil spring based on the calculation result and the determination data, and outputs the determination result.

Patent document 1: japanese patent laid-open No. 2003-16139
However, in the spring design system, when the specification data of the coil spring used for the calculation of the spring is insufficient, the coil spring that does not satisfy the expected result in the above test may be determined as data suitable for the coil spring. That is, the spring design system described above sometimes determines that a coil spring that should not be used originally is appropriate. Further, since components such as a vibration damping device for suppressing vibration of components constituting an automobile have a complicated structure as compared with a coil spring, erroneous determination due to a shortage of specification data may be more likely to occur.
On the other hand, in order to save labor required for a test itself using an actual vehicle, an automobile manufacturer or an automobile part manufacturer may collect the various data by performing a simulation. However, even when the simulation is performed, if the specification data is insufficient, erroneous determination due to the insufficiency of the specification data may be more likely to occur.

Detailed Description
[ first embodiment ]
An example of the vibration damping device design support device according to the first embodiment of the present invention will be described with reference to fig. 1 to 4. Fig. 1 is a view showing an example of the vibration damping device design support device according to the first embodiment of the present invention. As shown in fig. 1, the vibration damping device design support device 11 includes an adjustment unit 111, an acquisition unit 112, a determination unit 113, and a proposal unit 114.
The adjustment unit 111 adjusts the response characteristics of the operating elements included in the first vibration damping device for damping the vibration of the members constituting the actual vehicle. The first vibration damping device is, for example, a liquid seal bushing, and is mounted on a real vehicle used for a real vehicle test. The motion element is an element that performs a fixed motion by a member constituting the first vibration damping device or a combination of these members. The operating element includes a liquid sealed in the first vibration damping device. The response characteristic is a characteristic of a response of the motion element according to the vibration input to the motion element. The response characteristic is not necessarily limited to one type, and may include a plurality of types of characteristics of the motion element, such as amplitude dependency, attenuation characteristic, velocity dependency, and frequency characteristic. Here, the data indicating the response characteristics adjusted by the adjusting unit 111 is referred to as response characteristic data.
Fig. 2 is a diagram showing an example of the response characteristics adjusted by the vibration damping device design support device according to the first embodiment of the present invention. For example, as shown in fig. 2, the adjusting unit 111 sets a set value "a 111" for the response characteristic a11 of the predetermined operating element of the first vibration damping device. The set value here is a value that determines the response characteristic a 11. The adjusting unit 111 sets a set value "a 112" for the response characteristic a12 of the operating element of the first vibration damping device, and sets a set value "a 113" for the response characteristic a13 of the operating element of the first vibration damping device.
Specifically, the adjusting unit 111 adjusts the position of the member constituting the first vibration damping device or the shape or cross-sectional area of the flow path of the liquid sealed in the first vibration damping device by using a servo mechanism or an actuator, thereby setting these set values. When the liquid sealed in the first vibration damping device is an electrically viscous fluid, the adjustment unit 111 sets these set values by applying a voltage to the liquid using the electrodes to adjust the viscosity.
The adjustment unit 111 may set a plurality of set values, or may set a range of set values for determining the response characteristics, conditions expressed by numerical expressions, and the like, instead of setting one set value for determining the response characteristics of the operating elements of the first vibration damping device.
The acquisition unit 112 acquires vibration data and response data. The vibration data is data indicating vibrations input to the operating element when a real vehicle incorporating the first vibration damping device is used, for example, when a real vehicle test using the real vehicle is performed. The vibration data includes, for example, data indicating displacement, velocity, acceleration, and load causing vibration. The response data is data indicating a response of the motion element according to the vibration indicated by the vibration data. The response data includes, for example, data indicating the displacement, velocity, and acceleration of the motion element.
Fig. 3 is a diagram showing an example of vibration data acquired by the vibration damping device design support device according to the first embodiment of the present invention. For example, as shown in fig. 3, when vibration B11 is input to a predetermined operating element of the first vibration damping device in the actual vehicle test, the acquisition unit 112 acquires vibration data indicating a value "B111" describing vibration B11. Similarly, as shown in fig. 3, the acquiring unit 112 acquires vibration data indicating the value "B112" describing the vibration B12 when the vibration B12 is input to the predetermined operating element of the first vibration damping device, and the acquiring unit 112 acquires vibration data indicating the value "B113" describing the vibration B13 when the vibration B13 is input to the predetermined operating element of the first vibration damping device.
Further, instead of acquiring one value describing the vibration indicated by the vibration data, the acquisition unit 112 may acquire a plurality of values, or acquire a range of values describing the vibration, an expression describing the vibration, or the like.
Fig. 4 is a diagram showing an example of response data acquired by the vibration damping device design support device according to the first embodiment of the present invention. For example, in the case where the predetermined operating element of the first vibration damping device in the actual vehicle test shows the response C11 in accordance with the vibration B11 shown in fig. 3, the acquisition unit 112 acquires the response data indicating the value "C111" describing the response C11. Similarly, in the case where the predetermined operating element of the first vibration damping device in the actual vehicle test shows the response C12 in accordance with the vibration B12 shown in fig. 3, the acquisition unit 112 acquires the response data indicating the value "C112" describing the response C12. In addition, when the predetermined operating element of the first vibration damping device in the actual vehicle test shows the response C13 in accordance with the vibration B13 shown in fig. 3, the acquisition unit 112 acquires the response data indicating the value "C113" describing the response C13.
Further, instead of acquiring one value describing a response indicated by response data, the acquisition unit 112 may acquire a plurality of values, or acquire a range of values describing the response, an expression describing the response, or the like.
The determination unit 113 determines whether or not the response indicated by the response data satisfies the target response. The target response is a condition that response data of the operating element of the second vibration damping device, which is a vibration damping device incorporated in a commercially available real vehicle, needs to satisfy, and is determined by specifications of the real vehicle and the like.
The proposing unit 114 performs necessary determination for proposing the second vibration damping device. For example, the proposal unit 114 determines whether or not there is a second vibration damping device capable of performing a response indicated by the response data acquired by the acquisition unit 112. Specifically, the proposal unit 114 determines whether or not such a second vibration damping device is mounted in a directory. When it is determined that there is no second vibration damping device capable of performing the response indicated by the response data acquired by the acquisition unit 112, the proposal unit 114 determines whether or not the second vibration damping device capable of performing the response indicated by the response data acquired by the acquisition unit 112 can be manufactured.
When it is determined that there is a second vibration damping device capable of performing a response indicated by the response data acquired by the acquisition unit 112, the proposing unit 114 proposes the second vibration damping device based on at least one of the response characteristic data, the vibration data, and the response data.
Fig. 5 is a diagram showing an example of response characteristics, vibration, and response of each of the plurality of second vibration damping devices according to the first embodiment of the present invention. The vibration damping device D11, the vibration damping device D12, the vibration damping device D13, and the like shown in fig. 5 are, for example, placed in the catalog of vibration damping devices. The response characteristic a11 of the vibration damping device D11 is determined by the set value "a 111", the response characteristic a12 is determined by the set value "a 112", and the response characteristic a13 is determined by the set value "a 113". In addition, the vibration damping device D11 shows the response C11 described by the response data "C111" in the case where the vibration B11 described by the vibration data "B111" is input to the action element. Likewise, the vibration isolation device D11 shows the response C12 described by the response data "C112" in the case where the vibration B12 described by the vibration data "B112" is input to the action element, and shows the response C13 described by the response data "C113" in the case where the vibration B13 described by the vibration data "B113" is input to the action element. These cases are also the same for the vibration damping device D12 and the vibration damping device D13 shown in fig. 5.
Specifically, when vibration B11 described by vibration data "B111" shown in fig. 3 is input to the first vibration damping device and the operating element of the first vibration damping device shows response C11 described by response data "C111" shown in fig. 4, the proposal unit 114 proposes a vibration damping device D11 showing the same behavior. That is, the proposed part 114 proposes a second vibration damping device similar to the first vibration damping device. Similarly, when vibration B12 described by vibration data "B112" shown in fig. 3 is input to the first vibration damping device and the operating element of the first vibration damping device shows response C12 described by response data "C112" shown in fig. 4, the proposal unit 114 proposes a vibration damping device D11 showing the same behavior. In addition, when vibration B13 described by vibration data "B113" shown in fig. 3 is input to the first vibration damping device and the operating element of the first vibration damping device shows response C13 described by response data "C113" shown in fig. 4, the proposal unit 114 proposes a vibration damping device D11 showing the same behavior. These cases are also the same for the vibration damping device D12 and the vibration damping device D13 shown in fig. 5.
Alternatively, when the vibration B11 described by the vibration data "B111" shown in fig. 3 is input to the first vibration damping device and the operating element of the first vibration damping device shows the response C11 described by the response data "C111" shown in fig. 4, the proposing unit 114 proposes the vibration damping device D12 showing a behavior close to this behavior. That is, the proposal part 114 proposes a second vibration damping device having response characteristics relatively close to those of the first vibration damping device. In this case, the set value "a 121" indicating the response characteristic a11, the value "B121" describing the vibration B11, and the value "C121" describing the response C11 of the vibration damping device D12 shown in fig. 5 are values close to the set value "a 111" shown in fig. 2, the value "B111" shown in fig. 3, and the value "C111" shown in fig. 4, respectively, within predetermined ranges. This is also the same for other values shown in fig. 5.
Alternatively, the proposing unit 114 proposes a second vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data when it is determined that the second vibration damping device capable of producing the response indicated by the response data acquired by the acquiring unit 112 can be produced. Specifically, the proposing unit 114 proposes the second vibration damping device that is not placed in a directory or the like, based on the response characteristic data indicating the response characteristic adjusted by the adjusting unit 111 and the vibration data and the response data acquired by the acquiring unit 112.
The mode of the second vibration damping device proposed by the proposal part 114 is not particularly limited. For example, the proposed unit 114 proposes the second vibration damping device by displaying response characteristic data, vibration data, response data, and the like of the proposed second vibration damping device on a display.
Next, an example of processing performed by the vibration damping device design support device 11 will be described with reference to fig. 6. Fig. 6 is a flowchart showing an example of processing performed by the vibration damping device design support device according to the first embodiment of the present invention.
In step S111, the adjustment unit 111 adjusts the response characteristics of the operating elements included in the first vibration damping device.
In step S112, a real vehicle test is performed, and the acquisition unit 112 acquires vibration data and response data.
In step S113, the determination unit 113 determines whether or not the response indicated by the response data acquired in step S112 satisfies the target response.
In step S114, the adjustment unit 111 adjusts the response characteristics of the operating elements included in the first vibration damping device, and the process returns to step S112.
In step S115, the proposing unit 114 determines whether or not there is a second vibration damping device capable of performing a response indicated by the response data acquired in step S112. If it is determined that there is a second vibration damping device capable of performing the response indicated by the response data acquired in step S112 (step S115: yes), the proposing unit 114 advances the process to step S116. On the other hand, if it is determined that there is no second vibration damping device capable of performing the response indicated by the response data acquired in step S112 (step S115: no), the proposal unit 114 advances the process to step S117.
In step S116, the proposing unit 114 proposes a second vibration damping device in which the response characteristics are designed in advance based on at least one of the response characteristic data, the vibration data, and the response data, and ends the process.
In step S117, the proposing unit 114 determines whether or not the second vibration damping device capable of producing the response indicated by the response data acquired in step S112 can be produced. If it is determined that the second vibration damping device capable of performing the response indicated by the response data acquired in step S112 can be created (step S117: yes), the proposing unit 114 advances the process to step S118. On the other hand, if the proposal unit 114 determines that the second vibration damping device capable of performing the response indicated by the response data acquired in step S112 cannot be created (step S117: no), the process ends.
In step S118, the proposing unit 114 proposes a second vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data, and ends the process.
The vibration damping device design support device 11 according to the first embodiment of the present invention has been described above. The vibration damping device design support device 11 adjusts the response characteristics of the operating elements included in the first vibration damping device for damping the vibration of the components constituting the actual vehicle, and acquires vibration data and response data. Then, the vibration damping device design support device 11 proposes a second vibration damping device based on at least one of response characteristic data, vibration data, and response data indicating the response characteristic adjusted by the adjustment unit 111. Thus, the vibration damping device design support device 11 can effectively collect data required for determining a vibration damping device used in an automobile and can provide a vibration damping device that can exhibit desired response characteristics based on the data.
Further, the vibration damping device design support device 11 proposes a second vibration damping device in which response characteristics are designed in advance. Specifically, the vibration damping device design support device 11 proposes the second vibration damping device to be placed in a directory or the like based on at least one of the response characteristic data, the vibration data, and the response data. Thus, the vibration damping device design support device 11 can support the automobile manufacturer or the automobile component manufacturer to quickly select a vibration damping device that can exhibit a desired response characteristic.
The vibration damping device design support device 11 proposes a second vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data. Specifically, the vibration damping device design support device 11 proposes a second vibration damping device that is not placed in a directory or the like based on at least one of these data. Thus, even if the vibration damping device capable of exhibiting the desired response characteristic is not placed in a catalog or the like or sold on the market, the vibration damping device design support device 11 can provide a specific vibration damping device capable of exhibiting the desired response characteristic.
In the first embodiment, the first vibration damping device is mounted on the actual vehicle used in the actual vehicle test, but the present invention is not limited thereto. For example, the first vibration damping device may be a vibration damping device incorporated in a commercially available real vehicle.
The proposal section 114 may be realized by a device different from the device having the functions of the adjustment section 111, the acquisition section 112, and the determination section 113. In this case, the proposed unit 114 may transmit data indicating the second vibration damping device proposed in step S116 or step S118 shown in fig. 6 to another device, and notify the other device of the specific specification and the like of the second vibration damping device. The other device described herein may be the vibration damping device design support device 11, or may be other devices.
At least a part of the functions of the vibration damping device design support device 11 shown in fig. 1 may be realized by executing a program by hardware including a circuit unit (circuit). Examples of the hardware include a CPU (Central Processing Unit), an LSI (Large Scale Integrated Circuit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), and a GPU (Graphics Processing Unit). In addition, the above-described program may also be stored in the computer-readable storage medium 120 shown in fig. 7. Examples of the storage medium include an HDD (Hard Disk Drive), a flash Memory, a USB Memory, a ROM (Read Only Memory), and a DVD (Digital Versatile Disc). The above-described program may be a difference program for realizing a part of the functions of the vibration damping device design support device 11 shown in fig. 1.
The first embodiment of the present invention has been described above with reference to the drawings. However, the vibration damping device design support device 11 is not limited to the first embodiment described above, and various modifications, substitutions, combinations, and design changes can be made within the scope of the present invention defined by the claims.

[ second embodiment ]
An example of the vibration damping device design support device according to the second embodiment of the present invention will be described with reference to fig. 8 to 11. Fig. 8 is a view showing an example of the vibration damping device design support device according to the second embodiment of the present invention.
As shown in fig. 8, the vibration damping device design support device 21 includes an adjustment unit 211, an acquisition unit 212, a determination unit 213, and a proposal unit 214.
The adjustment unit 211 adjusts the response characteristics of the operating elements included in the virtual vibration damping device for damping the vibration of the members constituting the virtual vehicle, which is a simulated vehicle. The virtual vibration damping device is, for example, a virtual fluid seal bushing used in a simulation, and is incorporated into a vehicle in the simulation. The motion element is an element that performs a fixed motion by a member constituting the virtual vibration damping device or a combination of these members. The operation element includes a liquid sealed in the virtual vibration damping device. The response characteristic is a characteristic of a response of the motion element according to the vibration input to the motion element. The response characteristic is not necessarily limited to one type, and may include a plurality of types of characteristics of the motion element, such as amplitude dependency, attenuation characteristic, velocity dependency, and frequency characteristic. Here, the data indicating the response characteristics adjusted by the adjusting unit 211 is referred to as response characteristic data.
Fig. 9 is a diagram showing an example of the response characteristics adjusted by the vibration damping device design support device according to the second embodiment of the present invention. For example, as shown in fig. 9, the adjustment unit 211 sets a set value "a 211" for a response characteristic a21 of a predetermined operating element of the virtual vibration damping device. The set value here is a value that determines the response characteristic a 21. The adjustment unit 211 sets a set value "a 212" for the response characteristic a22 of the operating element of the virtual vibration damping device, and sets a set value "a 213" for the response characteristic a23 of the operating element of the virtual vibration damping device.
In addition, instead of setting a single set value for determining the response characteristic of the operating element of the virtual vibration damping device, the adjustment unit 211 may set a plurality of set values, or may set a range of set values for determining the response characteristic, conditions expressed by a numerical expression, and the like. Further, the adjustment unit 211 preferably adjusts the response characteristics of the operating elements of the virtual vibration damping device within the range of response characteristics that the vibration damping device mounted on the actual vehicle can exhibit.
The acquisition unit 212 acquires vibration data and response data. The vibration data is data indicating vibrations input to the operating elements in a simulation relating to the use of a virtual vehicle incorporating the virtual vibration isolation device. The vibration data includes, for example, data indicating displacement, velocity, acceleration, and load causing vibration. The response data is data indicating a response of the motion element according to the vibration indicated by the vibration data. The response data includes, for example, data indicating the displacement, velocity, and acceleration of the motion element.
Fig. 10 is a diagram showing an example of vibration data acquired by the vibration damping device design support device according to the second embodiment of the present invention. For example, as shown in fig. 10, when vibration B21 is input to a predetermined operating element of the virtual vibration damping device in a simulation relating to the use of the virtual vehicle, the acquisition unit 212 acquires vibration data indicating a value "B211" describing vibration B21. Similarly, as shown in fig. 10, when vibration B22 is input to a predetermined operating element of the virtual vibration damping device, the acquiring unit 212 acquires vibration data indicating a value "B212" describing vibration B22, and when vibration B23 is input to a predetermined operating element of the virtual vibration damping device, the acquiring unit 212 acquires vibration data indicating a value "B213" describing vibration B23.
Further, instead of acquiring one value describing the vibration indicated by the vibration data, the acquisition unit 212 may acquire a plurality of values, or acquire a range of values describing the vibration, an expression describing the vibration, or the like.
Fig. 11 is a diagram showing an example of response data acquired by the vibration damping device design support device according to the second embodiment of the present invention. For example, when a predetermined motion element of the virtual vibration damping device in a simulation related to the use of a virtual vehicle shows a response C21 in accordance with the vibration B21 shown in fig. 10, the acquisition unit 212 acquires response data indicating the value "C211" describing the response C21. Similarly, in the case where the predetermined operation elements of the virtual vibration damping device in the simulation relating to the use of the virtual vehicle show the response C22 in accordance with the vibration B22 shown in fig. 10, the acquisition unit 212 acquires the response data indicating the value "C212" describing the response C22. In addition, in the case where the predetermined operation elements of the virtual vibration damping device in the simulation related to the use of the virtual vehicle show the response C23 in accordance with the vibration B23 shown in fig. 10, the response data indicating the value "C213" describing the response C23 is acquired.
Further, instead of acquiring one value describing a response indicated by the response data, the acquisition unit 212 may acquire a plurality of values, or acquire a range of values describing the response, an expression describing the response, or the like.
The determination unit 213 determines whether or not the response indicated by the response data satisfies the target response. The target response is a condition that response data of an operating element of the vibration damping device incorporated in a commercially available real vehicle needs to satisfy, and is determined by specifications of the real vehicle and the like.
The proposing unit 214 performs necessary determination for proposing the vibration damping device. For example, the proposal unit 214 determines whether or not there is an anti-vibration device capable of performing a response indicated by the response data acquired by the acquisition unit 212. Specifically, the proposal unit 214 determines whether or not such an anti-vibration device is mounted in a directory. When it is determined that there is no vibration damping device capable of performing the response indicated by the response data acquired by the acquisition unit 212, the proposal unit 214 determines whether or not a vibration damping device capable of performing the response indicated by the response data acquired by the acquisition unit 212 can be manufactured.
When it is determined that there is an anti-vibration device capable of performing a response indicated by the response data acquired by the acquisition unit 212, the proposal unit 214 proposes an anti-vibration device mounted on an actual vehicle based on at least one of the response characteristic data, the vibration data, and the response data.
Fig. 12 is a diagram showing an example of response characteristics, vibration, and response of each of a plurality of vibration damping devices according to a second embodiment of the present invention. The vibration damping device D21, the vibration damping device D22, the vibration damping device D23, and the like shown in fig. 12 are, for example, placed in the catalog of vibration damping devices. The response characteristic a21 of the vibration damping device D21 is determined by the set value "a 211", the response characteristic a22 is determined by the set value "a 212", and the response characteristic a23 is determined by the set value "a 213". In addition, the vibration damping device D21 shows the response C21 described by the response data "C211" in the case where the vibration B21 described by the vibration data "B211" is input to the action element. Likewise, the vibration damping device D21 shows the response C22 described by the response data "C212" in the case where the vibration B22 described by the vibration data "B212" is input to the action element, and shows the response C23 described by the response data "C213" in the case where the vibration B23 described by the vibration data "B213" is input to the action element. These cases are also the same for the vibration damping device D22 and the vibration damping device D23 shown in fig. 12.
Specifically, when vibration B21 described by vibration data "B211" shown in fig. 10 is input to the virtual vibration damping device and the operating elements of the virtual vibration damping device show a response C21 described by response data "C211" shown in fig. 11, the proposal unit 214 proposes a vibration damping device D21 showing the same behavior. That is, the proposal unit 214 proposes the same vibration damping device as the virtual vibration damping device. Similarly, when vibration B22 described by vibration data "B212" shown in fig. 10 is input to the virtual vibration damping device and the operating elements of the virtual vibration damping device show a response C22 described by response data "C212" shown in fig. 11, the proposal unit 214 proposes a vibration damping device D21 showing the same behavior. When vibration B23 described by vibration data "B213" shown in fig. 10 is input to the virtual vibration damping device and the operating element of the virtual vibration damping device shows response C23 described by response data "C213" shown in fig. 11, the proposal unit 214 proposes a vibration damping device D21 showing the same behavior. These cases are also the same for the vibration damping device D22 and the vibration damping device D23 shown in fig. 12.
Alternatively, when vibration B21 described by vibration data "B211" shown in fig. 10 is input to the virtual vibration damping device and the operating element of the virtual vibration damping device shows response C21 described by response data "C211" shown in fig. 11, the proposal unit 214 proposes a vibration damping device D22 showing a behavior close to this behavior. That is, the proposal 214 proposes an anti-vibration device having response characteristics relatively close to those of a virtual anti-vibration device. In this case, the set value "a 221" indicating the response characteristic a21, the value "B221" describing the vibration B21, and the value "C221" describing the response C21 of the vibration damping device D22 shown in fig. 12 are values close to the set value "a 211" shown in fig. 9, the value "B211" shown in fig. 10, and the value "C211" shown in fig. 11, respectively, within predetermined ranges. This is also the same for other values shown in fig. 12.
Alternatively, when it is determined that the vibration damping device capable of making the response indicated by the response data acquired by the acquisition unit 212 can be created, the proposal unit 214 proposes a vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data. Specifically, the proposal unit 214 proposes the vibration damping device that is not placed in a directory or the like, based on the response characteristic data indicating the response characteristic adjusted by the adjustment unit 211 and the vibration data and response data acquired by the acquisition unit 212.
The proposed part 214 proposes an anti-vibration device, and the mode of the proposed part is not particularly limited. For example, the proposed unit 214 proposes the vibration damping device by displaying response characteristic data, vibration data, response data, and the like of the proposed vibration damping device on a display.
Next, an example of processing performed by the vibration damping device design support device 21 will be described with reference to fig. 13. Fig. 13 is a flowchart showing an example of processing performed by the vibration damping device design support device according to the second embodiment of the present invention.
In step S211, the adjustment unit 211 adjusts the response characteristics of the operating elements included in the virtual vibration damping device.
In step S212, a simulation is performed regarding the use of a virtual vehicle incorporating the virtual vibration damping device, and the acquisition unit 212 acquires vibration data and response data.
In step S213, the determination unit 213 determines whether or not the response indicated by the response data acquired in step S212 satisfies the target response.
In step S214, the adjustment unit 211 adjusts the response characteristics of the operating elements included in the virtual vibration damping device, and the process returns to step S212.
In step S215, the proposal unit 214 determines whether or not there is any vibration damping device capable of performing the response indicated by the response data acquired in step S212. If it is determined that there is any vibration damping device capable of performing the response indicated by the response data acquired in step S212 (yes in step S215), the proposal unit 214 advances the process to step S216. On the other hand, if it is determined that there is no vibration damping device capable of performing the response indicated by the response data acquired in step S212 (no in step S215), the proposal unit 214 advances the process to step S217.
In step S216, the proposing unit 214 proposes the vibration damping device in which the response characteristics are designed in advance based on at least one of the response characteristic data, the vibration data, and the response data, and ends the processing.
In step S217, the proposal unit 214 determines whether or not the vibration damping device capable of producing the response indicated by the response data acquired in step S212 can be produced. If it is determined that the vibration damping device capable of performing the response indicated by the response data acquired in step S212 can be manufactured (yes in step S217), the proposal unit 214 advances the process to step S218. On the other hand, if the proposed unit 214 determines that the vibration damping device capable of performing the response indicated by the response data acquired in step S212 cannot be created (step S217: "no"), the process ends.
In step S218, the proposing unit 214 proposes the vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data, and ends the process.
The vibration damping device design support device 21 according to the second embodiment of the present invention has been described above. The vibration damping device design support device 21 adjusts response characteristics of operating elements included in a virtual vibration damping device for damping vibration of a member constituting a virtual vehicle, which is a simulated vehicle, and acquires vibration data and response data. Then, the vibration damping device design support device 21 proposes the vibration damping device based on at least one of the response characteristic data, the vibration data, and the response data indicating the response characteristic adjusted by the adjustment unit 211. Thus, data required for determining the vibration damping device used in the automobile can be effectively collected by simulation, and a vibration damping device that can exhibit desired response characteristics can be provided based on the data.
Further, the vibration damping device design support device 21 proposes a vibration damping device in which response characteristics are designed in advance. Specifically, the vibration damping device design support device 21 proposes a vibration damping device to be placed in a directory or the like based on at least one of the response characteristic data, the vibration data, and the response data. Thus, the vibration damping device design support device 21 can support the automobile manufacturer or the automobile component manufacturer to quickly select a vibration damping device that can exhibit a desired response characteristic.
The vibration damping device design support device 21 proposes a vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data. Specifically, the vibration damping device design support device 21 proposes a vibration damping device that is not placed in a directory or the like based on at least one of these data. Thus, even if the vibration damping device capable of exhibiting the desired response characteristic is not placed in a catalog or the like or sold on the market, the vibration damping device design support device 21 can provide a specific vibration damping device capable of exhibiting the desired response characteristic.
The vibration damping device design support device 21 adjusts the response characteristics of the operating elements of the virtual vibration damping device within the range of response characteristics that the vibration damping device mounted on the actual vehicle can exhibit. As a result, the vibration damping device design support device 21 can perform a realistic simulation, and vibration damping devices actually placed in a catalog and vibration damping devices that can be actually manufactured can be proposed.
The aforementioned proposal unit 214 may be realized by a device different from the device having the functions of the adjustment unit 211, the acquisition unit 212, and the determination unit 213. In this case, the proposal unit 214 may transmit data indicating the second vibration damping device proposed in step S216 or step S218 shown in fig. 13 to another device via a network, and notify the other device of the specific specifications and the like of the second vibration damping device. The other device described herein may be the vibration damping device design support device 21 or may be other devices.
At least a part of the functions of the vibration damping device design support device 21 shown in fig. 8 may be realized by executing a program by hardware including a circuit unit (circuit). Examples of the hardware include a CPU (Central Processing Unit), an LSI (Large Scale Integrated Circuit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), and a GPU (Graphics Processing Unit). In addition, the above-described program may also be stored in the computer-readable storage medium 220 shown in fig. 14. Examples of the storage medium include an HDD (Hard Disk Drive), a flash Memory, a USB Memory, a ROM (Read Only Memory), and a DVD (Digital Versatile Disc). The above-described routine may be a difference routine for realizing a part of the functions of the vibration damping device design support device 21 shown in fig. 8.
The second embodiment of the present invention has been described above with reference to the drawings. However, the vibration damping device design support device 21 is not limited to the second embodiment described above, and various modifications, substitutions, combinations, and design changes may be made without departing from the spirit of the present invention.
In the vibration damping device design support device, the proposed part proposes the vibration damping device in which response characteristics are designed in advance.
In the vibration damping device design support device, the proposed part proposes the vibration damping device designed based on at least one of the response characteristic data, the vibration data, and the response data.
