摘　　要：高速列车曲线通过时,车辆系统受力状态比直线行驶更为复杂,加上列车复杂车轨耦合系统,列车牵引齿轮传动系统动力学响应难以预测,所以探究曲线通过参数对高速列车牵引齿轮传动系统动力学响应的影响,对于判断牵引齿轮传动系统运行状态是必要的。通过有限元缩聚与轨道车辆动力学相结合方法,运用SIMPACK软件建立了高速列车刚柔耦合精细化动力学模型,考虑齿轮箱、齿轮副和轮对的柔性,研究不同曲线通过参数对齿轮箱动力学响应的变化规律。结果表明超高值和曲线半径对齿轮箱各轴承振动加速度影响规律不同,对齿轮副传动误差峰峰值及径向力幅值变化影响较大,对齿轮时变啮合刚度、接触应力、轴向力和圆周力幅值变化影响较小。When high-speed train passes through curve path,the stress state of its vehicle system is more complex than that during its straight-line driving.Additionally,due to train with complex vehicle-rail coupled system,dynamic response of train traction gear transmission system is difficult to predict.So,it is necessary to explore effects of curve passing parameters on dynamic response of high-speed train traction gear transmission system for judging operation state of train traction gear transmission system.Here,through combination of finite element polycondensation and rail-vehicle dynamics,the software SIMPACK was used to establish the rigid-flexible coupled refined dynamic model of high-speed train.Considering flexibility of gearbox,gear pair and wheel set,influence laws of different curve passing parameters on dynamic response of gearbox were studied.The results showed that super elevation value and curvature radius of curve have different influence laws on vibration acceleration of each bearing in gearbox;they have larger effects on variations of peak-peak values of gear pair transmission error and radial force amplitude;they have smaller effects on variations of gear pair time-varying meshing stiffness,gear contact stress,and amplitudes of axial force and circumferential force.
