摘　　要：为掌握高速列车架悬式驱动装置振动特性,基于Adams/Rail建立了高速列车动车仿真模型,根据修改后的德国高速轨道谱生成了仿真模型轨道不平顺空间域波形作为轨道不平顺输入激励,据此进行不同车速下直线、曲线运行时的动力学仿真,仿真结果表明:高速列车架悬式驱动装置振动响应为非平稳随机信号,轨道状况以及车辆行驶速度对其影响很大。同时齿轮箱及牵引电机的振动主要体现在横摆、沉浮、侧滚及点头运动,当通过弯道时,两部件沉浮及侧滚振动位移存在较大均值,同时齿轮箱相对构架存在较大的摇头转角均值,且各向振动幅值基本与直线行驶时的振动幅值基本相同。In order to master vibration characteristic of high-speed train＇ s frame-mounted driving device, a simulation model of high-speed train＇ s motor car was established based on Adams/Rail, and track irregularity spatial-domain waveform was generated according to the modified German high-speed rail spectrum. At last, the dynamics simulations were carried out under different speeds. Simulation results show that the vibration response of driving device is a non-stationary random signal, and is affected by track conditions and speed. And the vibrations of gearbox and motor were mainly presented as yaw, ups and downs, roll and nedding motions. The ups and downs displacements and roll rotation angle of these two components show high mean values as the vehicle went around the curve, while vibration amplitudes are basically the same compared with straight driving.
