摘　　要：齿面点蚀及疲劳是高速运转摆线泵内外转子齿轮的主要失效形式,基于RecurDyn软件的多柔体动力学技术对某型摆线泵内外转子建立了刚柔耦合多体系统模型,对转子运动中的应力变化情况进行了仿真分析,得到摆线泵内外转子在啮合过程中的动态应力云图及最大应力节点应力历程曲线。通过不同齿形倒角参数最大接触应力点及应力值的仿真结果比较,确定合适的齿形参数。该方法已用于工程实践,可为齿形设计和优化提供参考。Tooth surface pitting and fatigue are the main failure forms of the inner and outer rotors of high-speed cycloid gear pump. Based on the multi-flexible body dynamics technology of RecurDyn, the rigid-flexible coupling multi-body system model of the inner and outer rotors of a type of cycloid gear pump is established, and the stress changes in the rotor movement are simulated and analyzed. The dynamic stress cloud map and the stress history curve of the maximum stress node of the inner and outer rotors of cycloid gear pump in the meshing process are obtained. By comparing the simulation results of the maximum contact stress point and stress value of different tooth profile chamfering parameters, the appropriate tooth profile parameters are determined. This method has been used in engineering practice and can provide reference for tooth profile design and optimization.
