摘要

为研究地铁列车冲击碰撞情景和吸能元件特性，依据列车动力学理论，用动力学软件对地铁列车冲击碰撞工况进行了仿真计算，模拟了缓冲器、压溃管和防爬吸能装置等吸能元件在冲击中的力学特性。以某型地铁车辆为例，计算了几类常见冲击工况，并研究了轮轨摩擦系数和车钩接触刚度对列车冲击碰撞过程的影响。

Abstract

To research metro vehicle crash scene and energy absorption equipment devices, based on the theory of vehicle dynamics,metro vehicle collision was simulated by dynamics software, and mechanical properties of buffer, folded-collapse tube, anti-climbing energy absorption device were simulated. Taking a metro vehicle as example, several common crash conditions were calculated, and influence of wheel-rail friction coefficient and coupler contact stiffness on vehicle collision was studied.
