| Abstract: | Aiming at vehicle crash in traffic accident ,this paper analyses the optimization method of structure energy absorption of vehicle front past in vehicle rear collision based on the non-linear finite element software ANSYS/ LS-DYNA, several key factors have been analyzed in the model-building process, and the feasibility of energy absorption through retangle hole in the surface of thin-wall structure is analysed. The optimized finite element model is got and used to analyse mechanical characteristics for vehicle bumper. |
