Embodiment Construction
[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0031] Embodiment 1 of the shearing resistance test method of the vehicle side wall column of the present invention: adopt such as figure 1 and figure 2 The shown test device, the test device includes a test bench, a pendulum force applying device and an image acquisition system, the test bench includes a bench body 1 and a side column 2 arranged on the bench body 1, for the bench body 1 In terms of structure, it is a truncated platform that is similar to the base of a real vehicle by fixedly connecting various beams to each other. It is the main support structure for carrying side columns 2 and top beams. Its specific structural form and strength requirements can be determined according to the actual situation. The situation is arbitrarily designed. The above-mentioned side wall columns 2 are vertically extended. In this embodiment, there are four si...

The invention relates to a testing method, a testing device and a testing bench rack for the shear resistance of vehicle side wall columns. The testing method for the shear resistance of vehicle sidewall columns comprises the following steps: (1) fixing the testing bench rack on the corresponding testing bench or on the ground; (2) applying an external lateral load to the side wall columns of thetesting bench rack; (3) collecting deformation data of the side wall columns. According to the testing method, the testing device and the testing bench rack for the shear resistance of vehicle side wall columns, the deformation of the side wall columns is observed by applying an external load to the side wall columns of the testing bench rack, thereby obtaining the shear resistance of the side wall columns. The testing method is relatively simple, and the whole vehicle test can be replaced only by the testing bench rack, the testing cost is low, and the testing process is prone to control.
Description
technical field [0001] The invention relates to a test method, a test device and a test stand for the anti-shear capacity of a vehicle side column. Background technique [0002] Vehicle safety has always been a topic of concern to all walks of life in the society. Vehicles carry a relatively large number of passengers. Once an accident is released, it is likely to cause mass death and injury, and the social influence is huge. Among them is an accident condition: when the vehicle hits a guardrail, the road breaks, or other vehicles rollover, or even falls into a cliff, the side of the vehicle will be subjected to the reaction shear force from the ground or the cliff, and the vehicle In the process of continuing to roll after a rollover, the joints on the side or top will also receive shear force from the ground or cliffs. When the shear force is large enough, the joints on the side and top of the vehicle will break , The top falls off, causing passengers to be thrown out of ...
