【 摘 要 】

In order to research subway impacting characteristics, a multi degree of freedom nonlinear dynamic model is established. By means of the numerical integration 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 buffers absorber damping energy and stroke of buffer. Different location of the vehicles can configure different capacity buffer.
