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。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.
