A measuring device comprises an elastomer selecting unit (71), a strain selecting and parameter obtaining unit (72), a longitudinal position identifying and strain combining unit (73) and an output unit (74) which are connected.

Description

 Wood field

 The ground method of safety on the track is especially

Hundreds of methods and devices. Background

 The track is still safer. In the ground safety method

 The most reliable and reliable method of self-safety is especially

The upper one hundred of the existing ones are usually the medium shear force, such as my current line "Horizontal, Baili Ground Volume Method" TB T 2489 94. The medium shear force is obtained by converting the elastic output of a part of the two parts, the cross-section output 哉 under the elastic rest and the force of the force. The force of the shearing force in the force-protected method is generally unrecognized. The size of the shadow is generally about 22 m. The effect of the small elastic surface is considered to be less than the maximum value of 80 or the forest value of 10 The tens of thousands of shots to capture the snake's work are not conducive to comprehensive performance.

The insufficiency of the force overcoming the hundreds of methods is that the shearing force sensor mounted on the side and the side plate and the backing plate are better matched to solve the same amount of support. However, the hundreds of methods introduced a special padding track on the side and the certain use of the track system is limited to the case of the ascending line. Snake". Content

 The purpose of this book is to provide the hundreds of methods and devices that are not supported by the ground and track system.

 The original is that without changing the orbit, the above-mentioned fruit is unsupported and can effectively follow the track or the same idea. The idea is that the support is determined by the top and the support is above. The upper two groups of different ones, the supporting equations, the existence of the equations solved by the equations, the possible hundred connections, the solution to the hundred, the support of the physical parameters is very necessary to rationally pass the other woods The equation is solved by solving the line.

 The one hundred methods provided in this section include the following a. The upper part of the force

 b. The slope of each of the output of the elastic combination and the output of the upper two outputs at the same hundred output

 c. The output of the elastic rest, the force of the force, the combination of the slopes obtained in step b, the combination of the two sets of outputs in step b, the combination output output support

d. Get a hundred sizes from the effective combined output. If the effective does not meet the requirements

In the case of 1 time, steps a, b, and c are performed along the track so that each combination output on each of the tops is matched to meet the requirements, and all the effective combined outputs on all the upper ones obtained are recombined to obtain a full combined output to satisfy the most demand. The value of the full combined output divided by the total combined output to the position is obtained in a hundred sizes.

最 由全 組合 輸出除以 向位置的全 組合 輸出的 值得到 百 大小。 In the case where the combined output on the upper side is less than 1 times effective, steps a, b, and c are performed along the track so that each combination output on the upper side has the same medium shear force and the medium cross-over output of each of the upper middle supports is satisfied. All that will be obtained above

The value that is most divided by the full combined output divided by the full combination of positions yields a hundred sizes.

 The one hundred devices provided by the present invention include a plurality of elastic rests that are elastically resting on the upper side.

 And the parameter elastic phase is connected to the output of the elastic combination and the upper two combinations. The slope of the output of each of the different output positions at the same output plane is supported by the support.

The position and the combination and the parameters are connected to the output of the elastic rest. And the combined coefficient combination of the slope obtained by the parameter and the two sets of output of the parameter are combined output output support support and

 The output to position and combination are connected to a 100-size output from a valid combined output.

 This is the effect of the existing wood.

 First, the measurement method and device of Muyou measured that the top of the fruit is not supported and the combination coefficient is generally constant. The combination of the most outstanding output characteristics is good or the purpose, etc. The accuracy is not high. It may not be comprehensive to the position.

 Second, the quantity method and device in the track and track system can not be used or the existing shear force is 10,000, the tens of thousands of forces, and the land can be obtained from Baidu Liye. And in the case of unclear effective capabilities, especially high-speed performance, research and safety, provide effective means with strong engineering

The process of the volume method of the force.

4 In Mode 1, the different positions, different supports, and The same hundred output elastic rest and the intersection of the two ends are distributed along the neutral direction, and ten of them represent the output of the support 1 and the output of the support, and the same position of the 表示 represents 0.5 times the support 0.5 output.

 5 The same type of elastic rest in the mode 1 is the same as the crossover and the combined output of the elastic rest to the crossover output, the 支撑 support and the output, .哉 Supported combination output, raft support subzero cross output, ten 哉 support subzero and output, 支撑 support sub-combination output can see the same combination of the same hundred, different support is also 哉. Hehe.哉 coincides with this hundred

 Supported by Mute.

 6 The strength of the mode 1 is arranged with the left support normal right, and the support function is more clear.

 7 In the way of the method 2, the flow of the tens of thousands of forces is indicated.

 In the mode 2, the output arrangement under different axis requirements is arranged in the order of the cycle.

 11 The output of the mode 3 is the same as the output of the mode.

 12 In this way, the flow of the tens of thousands of forces in the mode 3 is indicated.

 13 Liben's device. Hugh way

Mode 1 The one hundred methods provided in this example are intended to provide one hundred above and shorter.

 Method includes the following steps

 Step a 2 shows the force of one segment. The elastic L of the elastic rest 2 is usually not less than 2 times the support and not more than 2 times 2 times the support. Here, the L of the elastic rest 2 is equal to one L.

 The study and the following numbers indicate that a series of

 The intersections of the two ends mentioned in the distribution of the distribution to the forest are equal to the output under the arbitrary support, which can be equal to the effectiveness of the inertial combination of the 哉 traits characteristic support coefficient support and the position of the F-direction F. .

 General

 The support is elastic and the support underneath can be easily manipulated by means of 1 or a pad.

 The elastic suspension in the rail support and the output with the 哉 property can be combined with the output and the combination under the support

 =O z 1一 z 1一

 Among them, the lower cup elastic rest and the upper output support the characteristics of the squat traits under the support 1 and 0 respectively support and the elastic rest support means that the function of the force of the force is one hundred thousand and the same Under the support of the elbow, the combined proportional function of the proportional function 1 is 0, that is, 0.

Steps b 2, 4 show the intersection of the elastic rest 2 neutral position and the two sets of output along the sum of the elastic and the 2 O

 Support and support of elastic rest 2

Xx, x 2 x

 The slope of multiple hundred turns 20 a 2 / L by the position

 The slopes of the hundreds of outputs of the lower output are also similar, especially in the case where the output of the larger slope of the slope is 2 z.

 In addition to the same force to the position support 1 and the support 0, 4 can see that the same position can be supported by 1 and 0.5 times of support 0.5, and the same position can be supported by 0 and 0.5 times of support 0.5. The same is the same as the position of 0.5 times the support of 0.5 combined output on the combined output of the support 1 and the support 0 on the 可 elastically movable and has the characteristics of the 哉 property, the elastic output of the elastic support 2 under any support The ambiguous combination of Hugh's output at the bottom is feasible, and the situation is consistent because of the elastic rest and the characteristic of the 哉 property, which is determined by the output of the neutralization.

It is only as long as it is alive.

 The two sets of outputs under the same one hundred F can be obtained in the same way. The force is the same. The position support 1 and the support 0 will be 2, where X means 3 on the side, 4

 The position and position of the 3 and 4 can be obtained. The output of the two groups is not limited to other instruments such as sensors, sensors or the like. Generally

The 4 number of added value functions is reduced. Also due to the current finite element It is reasonable to get close to the two sets of outputs.

 Step c Elastic break output Baili action Combine the output in step b with the combination coefficient of the slope obtained in step b.

 According to the characteristics of the enthalpy of the table in step a, the non-哉 equation of the x + x + x x proportional coefficient can be obtained.

It can be seen that the combined output of the Baili action position 2 z or , 2 and 100 F is the size of the support method and the ground is 1 . This mode constant can be used for the position of the force before the step d.

 The constant can be obtained by the same force under the same force.

Step d is obtained by dividing the combined output by the most effective combination output. Oh or. Divide by the size of the applied hundred to get a hundred F. Effective "Yes wood It refers to the effective consideration of the work in the upper and lower cork gardens of the predetermined forest center. In the second and third modes of this embodiment, the combined output on the upper side of the phase is combined to obtain the full combined output. Therefore, the effective wave-reducing requirement of the combined output on the mode 2, 3, 1 is 45. Fully combined with 1 1 0.45 * 2 0.1 of 10 phases.

 6 is the first support normal second support constant can be seen that the different support components S, 2, S, 2 are very different, but the most combined output O O is very close to the state of the state method is not supported.

 However, if the best combined output meets the accuracy requirements, it may not be fully oriented. Mode 2

 1 shows the hundreds of methods provided in this way. The way to provide the hundreds of methods is as shown in the way 1 mode 1 performs a step a, b, c mode 2 above mode 1

 In step d, if the effective unsatisfied requirement is not less than 1 time when the combined output on the obtained 1 is valid, then the steps are included in steps c and d.

 . Steps along the reverse execution steps a, b, c to meet the requirements of each combination of 1 support output

 The abilities of each ability can be arbitrarily varied.

C2. step 1 The recombination of the output to obtain the full combined output of the step d of the full combined output is the combination of the full combined output in step c2 divided by the value of the full combined output of the position to obtain a combination of the top 100 and the top 7 The output function 61, the full combined output function 62 combined output 63, and the action position function 64 can be obtained by the full combined output algorithm.

 The one hundred and fifty-four, which are represented by the hundred 哉 53 of the present 即, that is, the one hundred smooth 基本, are substantially small.

 The position of the constant force of the constant force is the combined output of the two sets of output obtained in the combined coefficient combination b step obtained in step b before the obtained output is obtained. To the location.

 In the other phase, the combination of the output 63 is the middle 51, but the middle 51 is the center 52. The rest of the position velocity characteristics are generated by interpolation.

 In the step a of the present method, as shown in FIG. 8 , the L of the elastic rest 2 is also equal to a medium L. The number phase of only 4 is reduced by the value of the method 1. However, the accuracy of the fruit is not as clear as the number of 4, and the accuracy can be reasonably required. All the hundred,

 1 1 cycle Arrangement Elastic break 2 Overlap of the middle set.

 The output that is offset in the algorithm that is fully combined output in step c2 may not

It can be systemized without the obvious results. As shown in Figure 9, at more than 3 times 100, it can overlap with 2 2 cycles due to 2 degrees of elastic rest 2 Out will be offset in the phase algorithm and may not have to be within 1 cycle

 3 All layout 4 in the overlapping

A set of 10 is shown as being greater than 4 times, and can be arranged in a 3 1 cycle, 3 cycle overlap in 1 cycle, and a set of cycles can be arranged in a mixed cycle, such as in accordance with 8, 9 .

 However, if the best full-combined output meets the accuracy requirements, it may not be comprehensive to the position, but rather requires different directions.

Mode 3

 1 is shown in the hundreds of methods. Mode 2 This method is intended to provide hundreds of methods. Mode 2 is different. Mode 3 is effective.

 In mode 1, the efficiency of her reduction is less than 1 time. The general flexibility is 2 and the middle is as shown in 11.

 Mode 3 performs a step a, b, c in mode 1 mode 1 This mode is above mode 1

 In step d, if the effective unsatisfied requirement is less than 1 time when the combined output on the obtained 1 is valid, then the steps in steps c and d are included.

組合得到全 組合 輸出 此她全 組合 輸出的算法及參數 步驟d的 休操作步驟是將步驟c4中的全 組合 輸出除以 向位置的全 組合 輸出的 值得到 百 大小 即 12 C3. According to the reverse execution steps a, b, c, the combination output of each support is required to output the same

Combining the full combined output of the algorithm and the parameter step d of the algorithm is to divide the full combined output in step c4 by the value of the full combination output to the position to obtain a hundred size, ie 12

 The function obtained by the medium shear force is 61 1 The combination coefficient is considered, the function of the combined output obtained by the present mode 1 2, the function 62 of the full combined output of the algorithm, the middle output of the medium shearing method 63 1 The combination coefficient is considered, the present mode 1 Combined output 63 2. The action position function 64 is combined by the full combination output algorithm.

Under, get a hundred.

 This constant constant force is also the position of the combined output of the two sets of outputs in the combined b step, before the step d is output.

 The method is better. The method of adding the medium shear method to the edge is not the same.

 Mode 3 can be used to a certain extent and can be kept in the method.

 However, if the best full-combined output meets the accuracy requirements, it may not be comprehensive to the position, but rather requires different directions.

Mode 4

 The manner shown in Figure 13 provides a pre-method for the hundred devices 7 including

Elastic rest 71 in a period of 1 And the parameter 72 elastic rest 71 is connected to the slope of each of the hundreds of turns outputted under the support in the elastic crossover and in the elastic two-direction distribution and the different direct acting positions on the same hundred output planes.

 The combined output coefficient combination of the position and combination 73 and the parameter 72 connected to the output of the elastic rest and the slope obtained by the parameter 72 and the combined output of the two sets of parameters 72 are the size and the action position. Support and status

 The output 74 is connected to the position and the combination of 73 is obtained by the effective combined output. The size of the output is divided by the value output to the position combination to obtain a hundred-size output.

 The above-mentioned methods of rest can not be used to limit the equivalent of this content.
