摘要
对行星轮系接触疲劳的相关特性进行分析,建立了行星轮系的三维有限元模型,获取了定轴行星轮系的接触应力载荷谱和接触疲劳S-N曲线。利用ANSYS Workbench软件,以一组矿用行星轮系为实例进行接触疲劳仿真分析,得到了行星轮系的寿命和安全系数等相关参数。仿真结果表明:接触疲劳仿真分析为行星轮系的可靠性设计和结构优化提供了重要的保障。
3-D finite element model of planet gears was set up and contact stress load spectrum of fixed-axial planet gears and S-N curve of contact fatigue was obtained by analyzing related characteristics of contact fatigue of planet gears.Applying ANSYS Workbench software to analyzing contact fatigue of a set of mine planet gears,life and safety coefficient of planet gears was obtained.Simulation result showed that contact fatigue simulation analysis provided guarantee for reliability design and structure optimization of planet gears.
