Abstract

The invention discloses a dynamic performance parameter benchmarking device of an automobile thin-wall part in a collision experiment, and particularly relates to the technical field of automobile part detection, the technical scheme is that the dynamic performance parameter benchmarking device comprises a collision supporting seat and an impacted device, a collision plate is arranged on the inner side of the collision supporting seat, and a sliding groove is formed in the inner wall of the collision supporting seat; a connecting rear seat is arranged on the inner side of the sliding groove, a sliding rod is fixedly installed at the side end of the connecting rear seat and inserted into the inner side of the sliding groove, a pressing seat is fixedly installed at the lower end of the connecting rear seat, the impacted device is fixedly installed at the lower end of the pressing seat, the impacted device comprises a second positioning plate, and a fixing rod is fixedly installed at the lower end of the second positioning plate. A thin-wall part II is inserted into the outer wall of the fixing rod. The dynamic performance parameter benchmarking device of the automobile thin-wall part in a collision experiment has the beneficial effects that the thin-wall parts are arranged at different positions to be tested at the same time, and the thin-wall part fixing device is positioned, so that performance parameter detection data of the automobile thin-wall parts are more accurate and perfect.

Description

technical field [0001] The invention relates to the field of automobile component detection, in particular to a dynamic performance parameter benchmarking device for automobile thin-walled parts in collision tests. Background technique [0002] The simulation of car collision is to use finite element analysis software to solve and calculate the finite element model on a high-performance server, and simulate the car crash test. The main purpose is to verify the performance of the body in white and the restraint system. [0003] The existing technology has the following disadvantages: the position of the existing thin-walled parts of automobiles will be shifted during the collision test, and only one thin-walled part performance parameter detection is involved each time, resulting in loss of impact residual force, resulting in inaccurate and complete detection data. [0004] Therefore, it is necessary to invent a benchmarking device for dynamic performance parameters of automo...
