摘要：The bumper is an important part of a vehicle safety performance evaluation. In this paper, a domestic A-class car bumper as the object of study.CAE model was established by using HyperMesh software, and the finite element method is applied to solve the calculation of the model. The bumper were studied in C-NCAP and E.C.E R42 two different standards. The bumper is optimized by changing the structure size of the way. Appropriate to increase the thickness of the metal bar bumper can improve its safety performance, while its weight changed little.
