高速列车齿轮传动系统黏滑振动特性分析
|
摘要
为了分析黏滑振动时高速列车齿轮传动系统的扭转振动,考虑高速列车齿轮系统的时变啮合刚度和齿轮啮合误差,建立高速列车齿轮传动参数振动模型,分析了轮轨蠕滑率变化引起的齿轮传动系统扭转自激振动特性。结果表明,时变啮合刚度是齿轮传动系统发生谐波振动的主要原因,当蠕滑率超过最佳蠕滑率时,传动系统发生自激振动,系统响应出现稳定的极限环运动,自激振动不会改变系统振动主频,但使参数谐波振动更加明显,从而导致系统振动更为剧烈。
In order to study the torsional vibration of gear transmission system under slippage in high-speed train.A parametric vibration model of the gear transmission system is developed when the time-varying stiffness and the transmission error are considered.The nonlinear characteristic of selfexcited torsional vibration caused by wheel-rail creepage is analyzed.Numerical simulation results show that the time-varying mesh stiffness of meshing teeth pairs is the main cause of harmonic vibration of gear transmission system,when the wheel-rail creepage is over the best value,the self-excited vibration occurred and gear transmission system have the phenomenon of limited cycle in the same time,the self-excited vibration has no effect on the change of main frequency of the gear transmission system,but the harmonic response become more obvious,cause a strong vibration on the gear transmission system.
