摘要
为了研究驱动装置悬挂参数对机车横向动力学性能的影响,提出3个刚体的机车横向振动简单模型,结合轮对横向随机响应的特点,分析不同速度下,驱动装置悬挂参数对机车受迫振动的影响。同时讨论了驱动装置和构架质量、空心轴横向合成刚度、一系横向刚度以及驱动装置横向阻尼对驱动装置悬挂刚度选配及横向响应的影响情况。结果表明:机车运行速度达到160 km.h-1后,驱动装置悬挂应采用弹性架悬方式,刚度在0.01 MN.m-1数量级,计算结果与详细模型是吻合的;质量和一系横向刚度的变化对刚性架悬机车影响比较大,对弹性架悬机车的影响小;分析弹性架悬机车驱动装置的振动,必须考虑空心轴横向合成刚度和低速运行工况。
In order to research the influence of driving equipment suspension parameter on locomotive lateral dynamic performance, this thesis established a simplified model consisting of 3 rigid bodies for locomotive lateral vibration. By considering the characteristic of wheelsets movement on stochastic irregularity track, the driving equipment suspension effect on the system forced oscillation under different velocity is studied. At the same time, the mass of driving equipment and bogie frame, the lateral stiffness of hollow axle, the primary lateral stiffness and the lateral damp of driving equipment affecting the choice of driving equipment suspension stiffness and the lateral response are discussed. The numerical results show that the locomotive should be flexible driving motor suspensions with the stiffness of 0.01 MN ·m^-1 when it runs upwards of 160 km ·m^-1. The calculated results agree well with the detailed models. The varieties of the masses and primary lateral stiffness have great influence on rigid driving equipment suspension, but little impact on flexible suspension. The lateral stiffness of hollow axle must be taken into account under low speed to analyze the motor vibration with flexible driving motor suspensions in bogie frames.
