摘要

为了研究故障状态下高速列车齿轮箱轴承的振动响应，基于Hertz接触理论，考虑轴承外圈滚道上常见的剥离故障，利用三维建模软件SolidWorks和动力学软件RecurDyn，建立了高速列车齿轮箱轴承出现剥离故障时的动力学模型。通过对轴承的仿真分析可以看出，在经过外圈滚道上的剥离故障时，滚子的角速度出现周期性突变，产生打滑现象；滚子与外圈滚道故障处的冲击传递到保持架上，使其稳定性降低；外圈振动加速度频谱图在外圈故障特征频率的1倍频和2倍频处出现了峰值，根据理论分析，可以判定轴承出现故障的元件是外圈；外圈和滚子之间的接触力在故障处会周期性地增大和减小。

Abstract

In order to study the vibration response of gearbox bearings under fault conditions of high-speed train，based on Hertz contact theory，considering the spalling failure on the outer ring raceway of the bearing，and by using the 3D modeling software SolidWorks and dynamics software RecurDyn，a dynamical model of high-speed train gearbox bearing with spalling fault is established. Through the simulation analysis of the bearing，it can be seen that when the spalling failure on the outer ring raceway occurs，the angular velocity of the roller appears periodic mutation，resulting in slippage. The impact from the failure of the roller and outer ring raceway is transmitted to the cage，which reduces the stability. The vibration acceleration spectrum of the outer ring has peaks at 1 and 2 times the characteristic frequency of the outer ring. According to theoretical analysis，it can be judged that the outer ring is faulty. The contact force between the outer ring and the roller will increase and decrease periodically at the fault.
