Bumper Crash Simulation Study at Low-Speed Based on ANASYS Workbench

Honggang Li

Abstract

Accordring to ECE R42 regulation and using PRO/E software,a finite element model of automotive bumper is established,and the validity of the collision model is verified.Based on the ANASYS Workbench finite element method,the analysis of the energy-absorption of the bumper low-speed collisions is established.The results show that the most of the kinetic energy generated during the collision process can be absorbed by the automotive bumper device.Accordingly,the structural deformation of the car kept to a minimum.According to the simulation result and the energy absorbing characteristics of the thin-walled member,and some improvement measures are proposed.
