In this paper,the spot welds are simulated with the rigid beam elements,and according to the crash-boxs requirement of the spot welds density,spot welds location are evaluated using the topology optimization technology in OptiStruct.We obtained four new design location for the spot welds.By comparing the crash simulation results of four models,the optimal location of spot welds was found to be the one using six spot welds.This optimal location not only meets the demand for absorbing energy,but also has the least number of spot welds.
