摘要

针对某型坦克行星变速箱的K3行星排，为了研究故障齿轮对行星传动系统的动态特性影响，运用SolidWorks、Adams及ANSYS软件，建立其刚柔耦合动力学模型并进行联合仿真分析，验证了刚柔耦合模型相对于纯刚体模型在时域、频域上的振动响应；通过分析危险节点应力变化曲线，得到应力极大值时刻等效应力分布云图；阐明了轮齿剥落故障产生原因并模拟故障运行，与正常状态下的接触力、加速度仿真信号对比分析，得到了轮齿剥落故障的时域、频域响应特征。仿真结果可为行星变速箱的故障机理、故障诊断技术研究提供基础依据与理论支撑。

Abstract

For a certain type of tank planetary gearbox K3 planet row， in order to research the influence of the fault gear on the dynamic characteristic of planetary transmission system， by using Solid works， Adams and Ansys software， a rigid-flexible coupling dynamic model is established， as well as conducting joint simulation analysis. It is verified that the rigid-flexible coupling model has more obvious vibration response in the time and frequency domain than the pure rigid body model. By drawing the stress change curve of the dangerous node， the equivalent stress distribution cloud graph at the time of the maximum stress is obtained. The cause of gear spalling fault is clarified and fault operation is simulated. By comparing and analyzing the simulation signals of contact force and acceleration under normal conditions， the time and frequency response characteristics of gear spalling faults are obtained. The simulation results can provide basic basis and theoretical support for the research on the fault mechanism and fault diagnosis technology of the planetary gearbox.
