汽车的碰撞安全性直接关系到碰撞事故发生时司乘人员的生命安全，因此，加强汽车碰撞安全性的设计研究对汽车生产企业和汽车乘员都具有重要意义。将汽车碰撞的计算机仿真方法应用于实际车辆的开发研究之中，成功地模拟了实际道路上发生频率最高的整车正面碰撞，并着重对如何提高其碰撞性能进行了更深一步的数值模拟研究，取得了较好的效果。
The collision safety of a car is directly related to the life safety of the driver and passenger during the collision. Therefore, the design and study of enhancing the collision safety of a car is of great significance to both the automobile manufacturer and the car occupant. The computer simulation method of vehicle collision is applied to the actual vehicle development and research, successfully simulating the vehicle frontal collision with the highest frequency on the actual road and focusing on how to improve the collision performance of the vehicle in a deeper numerical simulation, Achieved good results.
