摘要
建立了动车组动车脱轨动力学模型,其中车辆脱轨后运行的接触碰撞模型直接采用更接近实际的接触模型。对动车组动车脱轨后的运行行为进行分析,并与转向架低速脱轨后运行行为的台架试验结果进行对比,发现动车转向架的齿轮箱和电机对车辆低速脱轨后的运行行为有较大的影响,齿轮箱和电机在一定程度上阻止车辆脱轨后继续横向移动,从而起到一定的脱轨安全防护作用。
The dynamic model of the EMU motor car is constructed.The crashing contact model of the running car after derailment uses a contact model which is closer to the actual.It shows that the gearbox and traction motor have a significant effect on the running behavior of the derailed car after series of analyses about the EMU motor car.The gearbox and motor can constrain the followed lateral displacement of the derailed wagon,and then will play aprotective effect of the derailment safety.
