碰撞模拟过程中焊点的影响

Effect of Spotweld in Simulations of Vehicle Crash

叙述了有限元分析中主要的焊点处理方式 ,提出碰撞模拟中常用的模拟方法 ,对常用的焊点模拟算法进行了分析 ,以某国产轿车整车碰撞模拟为例 ,提出在碰撞模拟中必须考虑焊点断裂特性 。

This paper presented how to deal with the spotweld in finite element analysis and compared the universal simulation methods.With the crash simulation of a certain domestic passenger-car,the failure of spotwelds must be considered to ensure the accuracy of the crash simulation.
