Description

  The present invention relates to an analysis work support apparatus, an analysis work support system, and a program for supporting analysis work of an analysis model.

  In recent years, design and development bases for product development have been expanded overseas. When designing products at each design and development site, the size of parts that can be procured locally, the mounting position, etc. may differ from the standard machine. For this reason, design changes have been made to the base standard machine by customized design that matches the local specifications. In such a customized design, in order to verify whether or not there is a problem with the contents of the design change, the influence of the change is analyzed using an analysis model, and the analysis result is evaluated. For example, when evaluating the strength or the like of a product in which a part of a part has been changed, an analysis model of the product is created, and the structural analysis of the product is executed using the analysis model.

Here, an evaluation area for analyzing the influence of the changed parts when customizing the computer apparatus will be described.
FIG. 13 shows an example of a conventional analysis model for evaluating the influence of heat generated by the CPU 201 installed on the substrate 200.

  The board 200 and the CPU 201 are shown as an analysis model created by CAD (Computer Aided Design) data (an example of design data). This analysis model is created in order to analyze the influence of heat generation by the CPU 201 around the substrate 200 and the CPU 201. In this example, an evaluation region 202 that is a substantially rectangular parallelepiped space is provided at the bottom of the substrate 200, and an evaluation region 203 that is also a substantially rectangular parallelepiped space is provided above the CPU 201. The evaluation areas 202 and 203 are specified with the xyz coordinates closer to the origin as the start point and the xyz coordinates farther from the origin as the end point. For example, if the coordinates of the start point are (a1, b1, c1) and the coordinates of the end point are (a2, b2, c2), the evaluation area 202 is indicated.

  The analysis device analyzes the state of heat accumulation in the evaluation regions 202 and 203 and accumulates the analysis results in the analysis result database. For example, the analysis apparatus can also analyze a change such as a heat accumulation caused by moving the position where the CPU 201 is installed to the center of the substrate 200. It is also possible to analyze changes in the air flow in the evaluation regions 202 and 203 due to the addition of fans to the board 200. The validity of the analysis result output by the analysis device is evaluated by an analysis specialist having analysis evaluation know-how for evaluating the analysis result. Since the analysis results are enormous data, appropriate evaluation by the analysis specialist is essential.

  By the way, if design and development bases are established in a plurality of countries, an analysis specialist who refers to the analysis results executed at each base and analyzes them is required. However, the analysis results cannot be properly evaluated at a base that does not have an analysis specialist. Therefore, a technique for sharing the know-how possessed by the analysis specialist among users at each base has been demanded.

  As this technology, “Analyzing procedures performed by engineers in the past and comments on analysis results can be stored in the storage means as the know-how of engineers, and other engineers can easily use analysis procedures with high importance. Japanese Patent Application Laid-Open No. H10-228561, which is described as “.”, Is disclosed.

JP 2005-182635 A

  As a method of sharing the know-how possessed by the analysis specialists at each site, the analysis report can be used to analyze the evaluation parameters used by the analysis specialists when evaluating the analysis results and the execution results performed using the evaluation parameters. It may be possible to leave it in a document such as However, in many cases, such a document does not contain information on the reason for the evaluation by the analysis specialist and the order in which the analysis specialist views the evaluation area.

  In addition, when changing the parts attached to the standard machine, the dimensions of the parts, etc. using the design data created by CAD, it is necessary to analyze which part the design change affects. is there. In such a case, the analysis specialist refers to the evaluation area based on many years of experience and knowledge, and determines whether or not a problem occurs in a part affected by the design change. However, designers who have little analysis experience (hereinafter referred to as “analysis beginners”) did not know which evaluation area should be referred to.

  And the experience of the analysis specialist who says what should be evaluated when analyzing or which evaluation area should be referred to cannot be extracted as information about the evaluation area and evaluation physical quantity, Such information was not accumulated in the database. For this reason, when changing the parts of the standard machine, it has not been possible to refer to past analysis result information (for example, the same or similar change contents) related to the change contents.

  In addition, the technique disclosed in Patent Document 1 only allows reference to knowledge stored in a database. For this reason, it was not easy for others to understand what kind of intention the analysis specialists performed evaluation.

  The present invention has been made in view of such a situation, and an object thereof is to enable other users to use analysis know-how possessed by an analysis specialist.

  The analysis knowledge creation unit according to the present invention creates analysis knowledge in which evaluation contents including operation logs performed for evaluating analysis results of design data changed in the past and design data changes are associated with each other. Then, the analysis knowledge is registered in the analysis knowledge database. The analysis knowledge reading unit according to the present invention reads from the analysis knowledge database and outputs analysis knowledge corresponding to the change contents of the design data changed in the same or similar to the change contents of the design data changed in the past.

According to the present invention, for example, when changing the design data of a standard machine, it is possible to use analysis know-how possessed by an analysis specialist by referring to analysis knowledge.

  The input / output device 2 outputs various operation instructions to the analysis work support device 1 in accordance with an input operation performed by the user on the operation unit 56 (see FIG. 2 described later). The input / output device 2 displays the analysis result, CAD data, analysis result evaluation log, and the like output by the analysis work support device 1 on the screen of the display unit 55 (see FIG. 2 described later).

  The analysis work support apparatus 1 includes an analysis knowledge reading unit 3 and an analysis knowledge creating unit 4. In the present embodiment, the relationship between the analysis purpose, design data change contents, analysis conditions for analyzing this design data, evaluation reason for analysis result evaluation, evaluation area, evaluation judgment value (physical quantity judgment threshold), etc. The collected data (see FIG. 6 described later) is referred to as “analysis knowledge”. Here, the analysis result evaluation is a case where an analysis specialist evaluates the validity of an analysis result obtained by analyzing design data changed in the past.

  First, the analysis knowledge reading unit 3 will be described. The analysis knowledge reading unit 3 extracts the change contents / analysis conditions and searches the analysis knowledge. At this time, the analysis knowledge reading unit 3 reads from the analysis knowledge database D2 the analysis knowledge corresponding to the change content of the CAD data that has been changed in the same or similar to the change content of the CAD data that has been changed in the past. Output to device 2. Here, the same change includes, for example, that a part included in a standard machine having a different production country or lot is changed to the same part as a part changed in the past. In addition, similar changes, for example, to the extent that parts of the standard machine (for example, fans) are the same but have different manufacturers and materials and do not significantly affect the analysis process of the product. Thus, it is included that the part is changed to a part having a different size from the part included in the standard machine. The analysis knowledge reading unit 3 includes a CAD data creation unit 31, a change content extraction unit 32, an analysis knowledge search unit 33, an analysis knowledge output unit 34, a CAD database D1, and an analysis knowledge database D2. In the figure, “database” is expressed as “DB”.

  The CAD database D1 stores CAD data in a tree configuration with a certain product (for example, PC) as a trunk and parts (for example, fans and boards) constituting the product as branches and leaves.

  The CAD data creating unit 31 reads CAD data (for example, design data of a standard machine) from the CAD database D1 based on an input operation performed on the input / output device 2, and creates CAD data. Then, the CAD data creation unit 31 stores the CAD data whose design has been changed in the CAD database D1. At this time, the CAD data creation unit 31 also saves the CAD data before the change and the CAD data after the change in the CAD database D1. In the following description, CAD data before change and CAD data after change are abbreviated as “CAD data before and after change”. Further, the CAD data creation unit 31 stores an operation log when an analysis specialist changes the CAD data created in the past as an analysis result evaluation log in the evaluation log database D3. Further, the CAD data creation unit 31 stores the analysis result obtained by analyzing the changed CAD data in the analysis result database D4.

  The change content extraction unit 32 compares the CAD data before change read from the CAD database D1 with the CAD data after change changed by the CAD data creation unit 31, and extracts the change content and analysis conditions. This change content / analysis condition is represented as CAD difference data such as a keyword or a numerical value, which is a feature extracted by the text mining from the CAD data before and after the change content extraction unit 32. The CAD difference data includes an operation log when the analysis specialist evaluates the analysis result. By this operation log, the analysis purpose, the evaluation reason, the evaluation area, the evaluation judgment value, etc. are analyzed for each change content. Conditions are indicated. Then, the change content extraction unit 32 stores the CAD difference data in the CAD database D1.

  The analysis knowledge search unit 33 searches the analysis knowledge stored in the analysis knowledge database D2 based on the change content / analysis condition extracted by the change content extraction unit 32. The change content / analysis condition is used as a key when the analysis knowledge search unit 33 searches the analysis knowledge. The change contents / analysis conditions include the part name, position information, temperature setting, flow rate setting, and the like changed by the CAD data creation unit 31. Then, the analysis knowledge search unit 33 outputs the searched analysis knowledge to the analysis knowledge output unit 34.

  The analysis knowledge output unit 34 outputs the analysis knowledge searched by the analysis knowledge search unit 33 to the input / output device 2. The input / output device 2 displays the analysis knowledge input from the analysis knowledge output unit 34 on the screen.

  Next, the analysis knowledge creation unit 4 will be described. The analysis knowledge creation unit 4 generates analysis knowledge in which evaluation contents including operation logs performed by an analysis specialist in order to evaluate analysis results of CAD data changed in the past and design data changes are associated with each other. Create and register the analysis knowledge in the analysis knowledge database D2. The analysis knowledge creation unit 4 includes an evaluation content extraction unit 41, an evaluation content connection unit 42, and an evaluation content registration unit 43 in addition to the evaluation log database D3 and the analysis result database D4.

  The evaluation log database D3 stores, as analysis result evaluation logs, operation logs such as physical quantity parameters and evaluation areas evaluated by the analysis specialist regarding the evaluation contents of the analysis results evaluated by the analysis specialist. This evaluation content includes an analysis purpose, an evaluation reason, an evaluation area, and an evaluation determination value.

The analysis result database D4 stores the analysis results of the analysis processing performed by the analysis specialist.
The evaluation content extraction unit 41 extracts the evaluation content from the evaluation log database D3 that stores the evaluation content of the analysis result of the CAD data analyzed by the analysis knowledge creation unit 4. The evaluation content extraction unit 41 can also extract the analysis result from the analysis result database D4 in which the analysis result of the CAD data analyzed by the analysis knowledge creation unit 4 is stored.

The evaluation content linking unit 42 associates the evaluation content extracted from the evaluation log database D3 by the evaluation content extraction unit 41 with the change content (CAD difference data) of the CAD data read from the CAD database D1.
The evaluation content registration unit 43 registers the evaluation content associated with the changed content as analysis knowledge in the analysis knowledge database D2.

<Example of computer hardware configuration>
Next, the hardware configuration of the computer 5 configuring each device of the analysis work support device 1 will be described.
FIG. 2 is a block diagram illustrating a hardware configuration example of the computer 5.

  The computer 5 is hardware used as a so-called computer. The computer 5 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, and a RAM (Random Access Memory) 53 connected to the bus 54. Further, the computer 5 includes a display unit 55, an operation unit 56, a nonvolatile storage 57, and a network interface 58.

  The CPU 51 reads the program code of software for realizing each function according to the present embodiment from the ROM 52 and executes it. In the RAM 53, variables, parameters, and the like generated during the arithmetic processing are temporarily written. The display unit 55 is, for example, a liquid crystal display monitor, and displays the results of processing performed by the computer 5 and the like to users (including analysis specialists and analysis beginners). For example, a keyboard, a mouse, or the like is used as the operation unit 56, and a user can perform predetermined operation inputs and instructions using these.

  Examples of the non-volatile storage 57 include a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, and a non-volatile memory card. Used. In addition to the OS (Operating System) and various parameters, the nonvolatile storage 57 stores a program for causing the computer 5 to function. For example, a network interface card (NIC) or the like is used as the network interface 58, and various types of data can be transmitted / received via a local area network (LAN), a dedicated line, or the like.

<Example of search processing for analysis result evaluation>
Next, a process in which the analysis work support apparatus 1 searches for analysis knowledge will be described.
FIG. 3 shows an example of processing performed by the analysis knowledge reading unit 3.

  Regardless of whether it is an analysis specialist or an analysis beginner, when the user performs an operation involving a new design change on the CAD data using the input / output device 2, the CAD data creation unit 31 reads the CAD data from the CAD database D1 ( S1). At this time, the CAD data creation unit 31 determines whether CAD data before and after the change exists in the CAD database D1 (S2). For example, when the user creates CAD data for the first time, since the CAD data before the change does not exist in the CAD database D1, the process ends. However, when the user changes a part of CAD data created in the past (for example, CAD data of a standard machine), the CAD data before the change exists in the CAD database D1.

  In step S2, if the CAD data creation unit 31 determines that the CAD data before the change exists in the CAD database D1, the CAD data before and after the change is output to the change content extraction unit 32. The change content extraction unit 32 compares the CAD data before the change with the CAD data after the change, and extracts text-based CAD difference data (S3). The CAD difference data includes design change information such as a part name and a part position included in the CAD data before and after the change. Then, the change content extraction unit 32 outputs the CAD difference data to the analysis knowledge search unit 33.

  Based on the CAD difference data input from the change content extraction unit 32, the analysis knowledge search unit 33 searches the analysis knowledge database D2 for analysis knowledge including evaluation content associated with the change content of the CAD data before and after the change ( S4). The change contents and analysis conditions used as keys when the analysis knowledge search unit 33 searches the analysis knowledge database D2 include keywords such as part names and parameter names that are the same as or similar to the CAD difference data. Then, the analysis knowledge search unit 33 outputs the search result to the analysis knowledge output unit 34. This search result includes, for example, information such as an evaluation area, a determination value, and an analysis purpose as a past analysis result evaluation.

  Then, the analysis knowledge output unit 34 outputs the searched analysis result evaluation to the input / output device 2, and the input / output device 2 displays the analysis result evaluation (S5). As a result, the user can grasp the points to be noted about the change of the CAD data by referring to the analysis results and analysis result evaluation logs of the analysis processing performed in the past with respect to the CAD data before and after the change.

<Example of analysis knowledge search tool>
FIG. 4 shows a display example of the analysis knowledge search tool 60.

  The analysis knowledge search tool 60 includes a CAD screen 61, a knowledge screen 62, a CAD difference data read button 63, a knowledge search button 64, and a cancel button 65. The analysis knowledge search tool 60 is a tool activated by the input / output device 2 separately from the CAD creation screen (not shown) by the CAD data creation unit 31, and its operation is mainly controlled by the analysis knowledge search unit 33.

  On the CAD screen 61, an analysis model constituted by CAD data read from the CAD database D1 by the analysis knowledge search unit 33 is displayed on the CAD screen 61. When the user presses the CAD difference data reading button 63, the analysis knowledge search unit 33 reads CAD difference data 75 (see FIG. 5 described later) from the CAD database D1. The CAD difference data 75 represents the difference between the CAD data before and after the change on a text basis as described above, and is data stored in the CAD database D1.

  Next, when the user presses the knowledge search button 64, the analysis knowledge search unit 33 searches the analysis knowledge database D 2 based on the change content included in the CAD difference data 75 and associates it with the change content indicated in the CAD difference data 75. Read the analysis knowledge. Then, the analysis knowledge output unit 34 displays the analysis knowledge on the knowledge screen 62. As shown in FIG. 4, the analysis knowledge output unit 34 displays the analysis knowledge in a tabular format on the knowledge screen 62. When the user presses the cancel button 65, the operation performed on the other buttons by the user is canceled.

<Example of CAD data before and after change>
FIG. 5 shows an example of the CAD difference data 75 extracted from the CAD data before and after the change by the change content extraction unit 32.

  The CAD database D1 stores pre-change CAD data 71 and post-change CAD data 72. The difference between the pre-change CAD data 71 and the post-change CAD data 72 is that the part C of the pre-change CAD data 71 is changed to the part E in the post-change CAD data 72. Then, the change content extraction unit 32 outputs the information regarding the part in the pre-change CAD data 71 as a pre-change CAD configuration data 73 as a text file. Similarly, the change content extraction unit 32 outputs the information regarding the parts in the CAD data 52a after the change as a changed CAD configuration data 74 as a text file.

  Thereafter, the change content extraction unit 32 compares the pre-change CAD configuration data 73 and the post-change CAD configuration data 74 on a text basis. And the change content extraction part 32 extracts the information regarding the components which are different before and after a change with the text file as CAD difference data 75, and preserve | saves it in CAD database D1. In the example of the analysis result evaluation search process, it is assumed that the screw position is also changed from 25 mm to 10 mm as the part C is changed to the part E.

<Configuration example of analysis knowledge database>
FIG. 6 shows a configuration example of the analysis knowledge database D2.

  The analysis knowledge database D2 is expressed in a table format including analysis knowledge number 80, analysis purpose 81, change contents / analysis condition 82, evaluation reason 83, evaluation area 84, and evaluation threshold value 85. The contents are stored as text.

The analysis knowledge number 80 stores a serial number for specifying the analysis knowledge for each record.
The analysis purpose 81 stores the analysis purpose input in the analysis purpose input field 101 of the analysis result evaluation tool 100 (see FIG. 9 described later). In the example of the analysis result evaluation search process, an analysis knowledge whose analysis objective 81 is “2” and whose analysis knowledge number 80 is “2” is shown in the analysis knowledge search tool 60 as a search result.

  The change content / analysis condition 82 stores the specific change content of the CAD data and the analysis condition when the analysis processing is performed. The data stored in the change content / analysis condition 82 includes the content of the CAD difference data 75 extracted from the CAD data before and after the change by the change content extraction unit 32.

The evaluation reason 83 stores an evaluation reason indicating the purpose of the analysis and how the analysis result was evaluated. The evaluation reason 83 is the evaluation reason input column 104 of the analysis result evaluation tool 100 (see FIG. 9 described later) or the evaluation reason input column 112 of the analysis purpose / analysis reason registration screen 110 (see FIG. 10 described later). The contents entered in.
The evaluation area 84 stores the state of heat accumulation, the air flow velocity, and the like in the evaluation area to be evaluated.
The evaluation threshold value 85 stores the parameter threshold value input to the parameter threshold value input field 102 of the analysis result evaluation tool 100.

  As described above, when a new design change is made by the CAD data creation unit 31, the change content extraction unit 32 extracts the change content from the CAD data before and after the change read from the CAD database D1, and obtains the CAD difference data 75. . Based on the CAD difference data 75, the analysis knowledge search unit 33 searches for the change contents of the CAD data included in the change contents / analysis condition 82 of the analysis knowledge database D2. If a keyword such as a part name that matches the CAD difference data 75 is included in the change content / analysis condition 82, it is displayed on the knowledge screen 62 of the analysis knowledge search tool 60 shown in FIG. The knowledge screen 62 includes an evaluation reason, an evaluation area, and an evaluation determination value of analysis result evaluation searched from the analysis knowledge database D2 by the analysis knowledge search unit 33. Thereby, the user can grasp | ascertain what kind of viewpoint the CAD data after a change should be evaluated based on the analysis result evaluation log with respect to the change content of CAD data performed in the past.

<Example of analysis knowledge creation and registration process>
Next, processing for registering the analysis knowledge created by the analysis work support apparatus 1 in the analysis knowledge database D2 will be described.
FIG. 7 shows an example of processing performed by the analysis knowledge creating unit 4.

  First, the evaluation content extraction unit 41 reads an analysis result evaluation log 115 (see FIG. 10 described later) from the evaluation log database D3, and reads an analysis result from the analysis result database D4 (S11).

  Next, the evaluation content extraction unit 41 checks whether or not the read analysis result evaluation log includes information such as an evaluation area and an evaluation determination value operated by an analysis specialist (S12). If such information is included, an evaluation area and an evaluation determination value are extracted from the analysis result evaluation log (S13). If these pieces of information are not included, the evaluation content extraction unit 41 ends the process.

  Next, the evaluation content extraction unit 41 checks whether or not the analysis result evaluation log includes information such as the analysis purpose (S14). If the analysis result evaluation log includes information such as the analysis purpose, the evaluation content extraction unit 41 extracts the analysis purpose and the evaluation reason from the analysis result evaluation log (S15).

  Next, the evaluation content linking unit 42 associates the analysis purpose and evaluation reason extracted by the evaluation content extraction unit 41 with the CAD data before and after the change (S16). By this processing, the change contents shown in the CAD difference data 75 are associated with the analysis purpose / evaluation area and the evaluation determination value of the analysis performed on the CAD data after the change. Then, the evaluation content registration unit 43 analyzes the change content indicated in the CAD difference data 75 and the analysis purpose, the evaluation reason, the evaluation area, and the evaluation determination value of the analysis performed on the CAD data after the change as analysis knowledge. Register in the knowledge database D2 (S17). Each data registered in the analysis knowledge database D2 corresponds to each item displayed on the knowledge screen 62 of the analysis knowledge search tool 60.

The pre-change CAD data 71 is displayed in the pre-change CAD data display field 91, and the post-change CAD data 72 is displayed in the post-change CAD data display field 92.

  In the example of the creation and registration process of analysis knowledge, analysis knowledge is created for the contents of temperature evaluation performed when the dimension of the part B indicated in the CAD data 71 before change is changed from 10 mm to 20 mm. Therefore, although strictly different from the post-change CAD data 72 in FIG. 5, the post-change CAD data for which temperature evaluation is performed will be described as the post-change CAD data 72 in order to facilitate understanding of the description.

  Next, when the user presses the difference extraction button 94, the CAD difference data 75 of the pre-change CAD data 71 and the post-change CAD data 72 is extracted. When the user presses the difference data output button 95, CAD difference data 75 extracted from the CAD data before and after the change by pressing the difference extraction button 94 is output to the input / output device 2. It is assumed that the CAD difference data 75 includes contents obtained by changing “the dimension of the part B from 10 mm to 20 mm” indicated by the analysis knowledge number “1” of the analysis knowledge database D2 illustrated in FIG. The CAD difference data 75 output to the input / output device 2 is stored in the CAD database D1.

  When the user presses the analysis result evaluation log association button 96, the analysis result evaluation tool 100 (see FIG. 9 described later) is called. In the analysis result evaluation tool 100, since an analysis model based on CAD data read from the CAD database D1 is displayed on the input / output device 2, the analysis specialist inputs specific numerical values while viewing the displayed analysis model. Can do. If this analysis result evaluation tool 100 is used, it is possible to register the operation log of the analysis specialist in the analysis knowledge database D2 in association with the CAD difference data 75.

  When the user presses the analysis purpose / analysis reason registration button 97, an analysis purpose / analysis reason registration screen 110 (see FIG. 10 to be described later) is displayed on the input / output device 2, and information on what purpose and why analysis is performed. Can be entered as text. With regard to the analysis purpose / analysis reason input on the analysis purpose / analysis reason registration screen 110, the operation log of the analysis specialist can be registered in the analysis knowledge database D2 in association with the CAD difference data 75. When the user presses the cancel button 98, an operation performed by the user on another button is canceled.

<Example of analysis result evaluation tool>
FIG. 9 shows a display example of the analysis result evaluation tool 100.

  The analysis result evaluation tool 100 is displayed on the screen of the input / output device 2 by the CAD data creation unit 31.
