Considering the coupling effects of the tribology and dynamics, a dynamic pitting evolution model of planetary gear sets is developed. A fast dynamic load distribution algorithm is proposed to obtain the dynamic contact load considering complex pitting topography. Then the mixed elastohydrodynamic lubrication theory is adopted to acquire the tribological parameters. Combing the dynamic load and Zaretsky's fatigue criterion, a contact fatigue model is developed to predict the pitting topography during the degradation process. An iterative algorithm framework is developed to realize the topographical updating in the dynamic pitting prediction. The effectiveness of the proposed model is demonstrated using two experimental examples. The probability distribution of the pitting location is investigated using the proposed model. It is revealed that the gamma distribution is more consistent with the pitting distribution along the involute direction than the normal distribution. Owing to the “competition mechanism” of the pitting and surface wear, the pitting center approaches the pitch point with the increase of the surface roughness. The proposed model is capable of evaluating tribo-dynamic behaviors of planetary gear sets during the life-cycle degradation process of pitting failure. Moreover, it can provide theoretical guidance for the pitting fault mechanism and model-based fault diagnosis.

基于摩擦动力学的行星齿轮组点蚀演化模型:一种拓扑更新方法

考虑摩擦学和动力学的耦合效应,建立了行星齿轮组的动态点蚀演化模型。为了获得考虑复杂点蚀形貌的动态接触载荷,提出了一种快速动态载荷分布算法。然后采用混合弹流润滑理论获取摩擦学参数。结合动态载荷和 Zaretsky 疲劳准则,建立了接触疲劳模型来预测退化过程中的点蚀形貌。开发了一种迭代算法框架来实现动态点蚀预测中的地形更新。使用两个实验示例证明了所提出模型的有效性。使用所提出的模型研究了点蚀位置的概率分布。结果表明,伽马分布与沿渐开线方向的点蚀分布比正态分布更一致。由于点蚀和表面磨损的“竞争机制”,点蚀中心随着表面粗糙度的增加而接近节点。所提出的模型能够评估行星齿轮组在点蚀失效的生命周期退化过程中的摩擦动力学行为。此外,它还可以为点蚀故障机理和基于模型的故障诊断提供理论指导。随着表面粗糙度的增加,点蚀中心逐渐接近节点。所提出的模型能够评估行星齿轮组在点蚀失效的生命周期退化过程中的摩擦动力学行为。此外,它还可以为点蚀故障机理和基于模型的故障诊断提供理论指导。随着表面粗糙度的增加,点蚀中心逐渐接近节点。所提出的模型能够评估行星齿轮组在点蚀失效的生命周期退化过程中的摩擦动力学行为。此外,它还可以为点蚀故障机理和基于模型的故障诊断提供理论指导。
