A test device and method for dynamic bending resistance of automobile side pillars hitting key parts

Abstract

The invention discloses a device and method for testing dynamic bending resistance performance of key parts in an automobile side post impact in order to overcome defects of large resource consumption and long development cycle caused by complete vehicle crash tests which are generally adopted in safety performance development for automobile side post impact currently. The testing device comprises a support assembly installed on a rigid wall for fixing a testing member and a collision structure applying a dynamic impact on the testing member. The device and method for testing the dynamic bending resistance performance of the collision key parts of the automobile side column can perform a dynamic impact test on the testing member installed on the support assembly through the collision structure, can simulate a bending resistance performance of the testing member under a high-speed impact, wherein the deformation speed of the testing member accords with that of the testing member in the integral automobile test, and thus can more accurately and efficiently perform an optimization design on the testing member. Furthermore, the support assembly and the collision structure are wide in universality, simple in structure, low in cost, easy to set up, easy to install and dismount, and can be repeatedly used and tested for many times.

Description

technical field [0001] The invention belongs to the technical field of automobile safety design, and relates to the design of a test method for the dynamic bending resistance performance of automobile parts. Specifically, the present invention relates to a testing device and method for the dynamic bending resistance performance of the automobile side pillar bump key component. Background technique [0002] The side pillar impact of a car is an important crash safety test item for examining the side impact performance of a car in addition to the side impact. At present, the side pillar impact is a routine test item in European, American, Latin and other national regulations and automobile evaluation regulations, and it is likely to be introduced into C-NCAP or relevant Chinese regulations in the future. Therefore, whether it is to meet the export needs of Chinese brand cars or to prepare for future domestic regulations, the impact performance of the side pillar of the car is...
