Problems solved by technology

[0004] However, this fixation is not strong enough to allow the barrier to move during said collision
Once the barrier moves, the crash conditions will change, the crash test data will be wrong, and eventually the crash test will fail

Embodiment Construction

[0027] figure 1 is a schematic front view of a vehicle crash test barrier fixing device according to an embodiment of the present invention, as figure 1 As shown, this embodiment provides a barrier fixing device for a vehicle crash test, and the barrier fixing device may generally include: a collision wall 1, a collision barrier 2, a fixing member 5 and a plurality of barrier connections Item 7. The collision wall 1 can have a plurality of grooves 11 . The barrier connectors 7 can be multiple, the barrier connectors 7 can be selectively held in the plurality of tanks 11, and the barrier connectors 7 can move along the tanks 11 . It should be noted that the plurality of barrier connectors 7 can be provided in one-to-one correspondence with the plurality of tanks 11; it is also possible to connect some of the plurality of barrier connectors 7 according to specific usage requirements. One is selectively held in some corresponding ones of the plurality of tanks 11. Said barri...

Abstract

The invention provides a barrier fixing device of vehicle collision test, and relates to vehicle collision test. The barrier fixing device comprises a collision wall, barrier connecting pieces, a collision barrier and fixing pieces, wherein the collision wall includes multiple grooves; the barrier connecting pieces can be maintained in the grooves selectively and move along the grooves; the collision barrier is used for offset or angular collision and connected with the barrier connecting pieces; and the fixing pieces can be connected with the barrier connecting pieces, and fit to the sidewall of the collision wall at one end of the grooves to prevent the barrier connecting pieces from moving in the grooves. The movement degree of freedom of the barrier connecting pieces along the groove direction is reduced by the fixing pieces, the barrier connecting pieces are prevented from moving along the groove direction, and the problem that the collision barrier connected with the barrier connecting pieces moves in the collision process is solved fundamentally.

Description

technical field [0001] The invention relates to a vehicle collision test, in particular to a barrier fixing device for a vehicle collision test. Background technique [0002] In the offset crash or angle crash test of the vehicle, it is necessary to install a rigid offset crash barrier on the frontal impact wall. The offset collision barrier needs to deviate from the center of the vehicle track by a corresponding distance in accordance with the relevant regulations of the automobile collision test, and then the vehicle hits the collision wall to perform the offset collision or angle collision test. For example, when a frontal 25% offset collision is performed, the collision-side end surface of the offset collision barrier needs to be deviated from the center plane of the track by 25%, so as to conduct a 25% offset collision test. [0003] Existing offset collision or angle collision test barriers include a collision wall, the wall of the collision wall is fixed with an iron...
