摘　　要：汽车追尾事故发生率较高,对汽车损害大。针对这一问题,对汽车进行几何建模,通过几何前清理、网格划分、边界条件设置得到汽车有限元模型,并进行仿真分析。在仿真分析中,更改汽车有限元模型中的车尾质量,使汽车在满足轻量化要求的同时,达到追尾事故安全优化的目的。The accident rate of car rear end collision is relatively high,which is very harmful to the car.In response to this issue,the car was geometrically modeled,and the car’s finite element model was obtained through geometric pre cleaning,grid division,and boundary condition setting,and simulation analysis was performed.In the simulation analysis,the mass of the rear end of the car’s finite element model was changed,so that the car could meet the requirement of lightweight and achieve the goal of safety optimization for the rear end collision accident.
