摘要
建立了行星轮系刚柔耦合多体动力学仿真模型,应用多体动力学仿真分析软件RecurDyn,仿真计算了行星轮系齿轮在完整工作周期所给定最危险工况下的动力学响应,得到了刚柔、柔柔齿轮副之间的动态接触力,与理论值比较吻合;同时得到了柔性行星齿轮和太阳轮的动态等效应力分布云图,以及任意节点的等效应力,分析出行星轮破坏的原因,为行星轮的动态优化设计和灵敏度分析提供参考.
In this study,a rigid-flexible coupling model for planetary gear system is established using dynamical simulation. In this regard, the entire working cycle is calculated based on the multi-body dynamical simulation software, i. e. RecurDyn＆TM.Meanwhile, the dynamical responses are acquired under the toughest working conditions. In concordance with theoretical values, the dynamic contact forces between rigid-flexible and flexible-flexible gear pair are obtained. Afterwards, the contour diagrams of dynamic equivalent stresses, together with arbitrary node stresses, are attained for flexible planetary and solar gears. Finally, the damages to planetary gears are elaborated for the purposes of optimal design and sensitivity analysis.
