Front anti-collision beam assembly lightweight designing method based on independent assessment working condition

Abstract

The invention discloses a front anti-collision beam assembly lightweight designing method based on an independent assessment working condition and solves the problems that influence of various collision working conditions on performance of a front anti-collision beam assembly is considered insufficiently and verifying of the performance is only conducted in a whole vehicle at the stage of structural improving and lightweight designing of the front anti-collision beam assembly. The method includes steps: 1), selecting various collision working conditions: selecting collision working conditions various in form and capable of comprehensively reflecting anti-collision performance of the front anti-collision beam assembly; 2), determining a lightweight design performance target of the front anti-collision beam assembly: determining a performance target of the front anti-collision beam assembly on the basis of the anti-collision performance of the whole vehicle in each collision working condition; 3), establishing the independent assessment working condition of the front anti-collision beam assembly and verifying effectiveness of the same: establishing the independent assessment working condition of the front anti-collision beam assembly, and verifying the effectiveness of the independent working condition; 4), performing lightweight designing on the front anti-collision beam assembly on the basis of the independent assessment working condition: using the determined performance target of the front anti-collision beam assembly as a constraint condition and the independent assessment working condition as a carrier to perform lightweight designing on the front anti-collision beam assembly.

Description

technical field [0001] The invention relates to a design method in the field of automobile passive safety research, more precisely, the invention relates to a lightweight design method of a front anti-collision beam assembly based on independent evaluation conditions. Background technique [0002] There are many types of vehicle frontal crash test conditions, including different collision speeds, different barrier forms, and different overlapping areas between the vehicle and the barrier. For different collision conditions, due to the different boundary conditions, the focus of vehicle collision safety investigation is also different. Correspondingly, the performance requirements for the front anti-collision beam assembly in vehicle safety are also slightly different. At present, most of the structural optimization and lightweight design methods of the front anti-collision beam assembly are aimed at a single working condition, and there is a lack of guiding methods for the d...
