Or, to simplify it further, only simulate the relative motion between the side structure of the body-in-white and the seat, and simulate the side impact, which is generally simulated by using an acceleration slide table, which is a very rough method, because the The amount of intrusion and the intrusion speed of the side have not been simulated, which is very different from the actual test results
[0003] At the same time, for the research and development of side collision of vehicles, there are many collision forms, such as moving deformable barrier (MDB-Moving Deformation Barrier), side pillar collision, Chinese national standards, European regulations, Chine

Example Embodiment

[0024] Example 1

[0025] Such as figure 1 , figure 2 As shown, the vehicle side impact simulation test structure includes an acceleration sliding table 10, a sliding table rail 1 and a body-in-white 8. The bottom of the body-in-white 8 is provided with a support plate 6 corresponding to the positions where the front and rear axles should be set. The support plate 6 is connected with a cross beam 7 perpendicular to the slide table rail 1, and the cross beam 7 is slidably arranged above the slide table rail 1 and makes the bottom of the white body 8 parallel to the horizontal plane. The white body 8 and the support plate 6 are mutually fixed The position is consistent with the position where the body of the actual vehicle is connected to the chassis system. The support plate 6 is parallel to the slide table track 1 and the end of the support plate 6 close to the acceleration slide table 10 is respectively connected with a brake mechanism 4 by a rope 5, which is parallel to the sl...

[0034] Example 2

[0035] Such as Figure 4 As shown, the bullet car is an MDB angle bullet car 9. For the angled side collision simulation, take the American standard FMVSS 214 as an example. The MDB angle bullet car 9 has an angle. Similarly, the MDB angle bullet car 9 is counterweighted according to the standard definition. The center line of symmetry of the acceleration slide 10 is at an included angle of 63 degrees. The white body 8 fixes the support plate 6 at an angle defined by the standard. Similarly, the support plate 6 is parallel to the horizontal plane, that is, it can slide on the horizontal plane, and the rope 5 and brakes The mechanism 4 traction, the brake mechanism 4 can set the traction force when the rope 5 is released. In a specific test, the set traction force can be obtained by actual wheel and ground friction, which can be obtained through actual measurement or calculation, namely:

[0040] Example 3

[0041] Such as Image 6 As shown, the bullet car is a column collision bullet car 11, the column collision bullet car 11 and the acceleration slide 10 are an integrated structure, and the collision execution component is a collision column. Others are the same as in Example 1.

[0042] For side column collision tests, such as the EURO-NCAP (European New Car Evaluation) test, that is, the collision column is stationary, and the vehicle collides with the collision column at a specified speed and angle. This is the same as the aforementioned dynamic deformable barrier ( MDB) It is different to hit the side of a stationary vehicle, but the present invention can also be used for simulation measurement. Such as Image 6 , Figure 7 As shown, the acceleration slide 10 and the column collision bullet car 11 are always connected together. The front end of the column collision bullet car 11 is provided with a collision column of the size specified by the standard. When th...

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a vehicle side collision simulation test structure and a test method thereof. Background technique [0002] In the passive safety development of automobiles, the acceleration slide table and deceleration slide table are usually used to simulate the side collision of the vehicle, and the deformation or intrusion amount, deformation speed or intrusion speed of the vehicle side structure in the collision test is simulated to realize the The simulation of vehicle side collision, this method is to cut the vehicle body into sections, and use some energy-absorbing materials to simulate the intrusion amount and intrusion speed in each section. At the same time, the movement of the seat and the vehicle side The relative motion of the structure is simulated, which is generally simulated by a deceleration slide table. This method requires a large number of calibration tests to com...
