基于现有的多自由度非线性动力学振动模型，通过MATLAB数值模拟方法，研究了在不同碰撞速度下，六车编组列车的连挂冲击特性。结果表明：车辆连挂碰撞时，随着碰撞速度的增加，距离碰撞分界面越近，缓冲器阻尼消耗的能量、缓冲器最大行程增大率越大；不同位置的车辆可以配置不同容量的缓冲器。

In order to research subway impacting phenomena ,a multi degree of freedom non-linear dynamic model is established .By means of numerical simulating method ,the impacting characteristics of six vehicles groups are researched .The results show that when impacting phenomena between two vehicle groups take place ,the closer distance impacting interface , the greater buffer′s absorber damping energy and stroke of butter ;different location of the vehicles can configure different capacity buffer .
