RV减速器摆线针轮传动多体动力学研究

摆线针轮啮合传动部分是RV减速器的关键结构之一,基于多体动力学构建虚拟样机进行仿真分析是研究RV减速器动态特性的常用方法。在不同载荷和不同工作环境下,基于多刚体动力学对RV减速器进行了仿真分析,仿真结果直观显示了不同工作环境下摆线针齿啮合特性变化情况。采用刚柔耦合技术,提取连续节点应力变化曲线进行分析,确定了啮合时最大接触力的位置和大小,为后续对修形方式的研究和改进提供了理论基础。

Study on Multi-body Dynamics of Cycloidal Pin Wheel Transmission of RV Reducer

The meshing transmission part of the cycloidal pin wheel is the key structure of the RV reducer,the simulation analysis of virtual prototype based on multi-body dynamics is a common method to study the dynamic characteristics of the RV reducer.Taking into account different loads and different working conditions,the RV reducer is simulated and analyzed based on multi-rigid dynamics.The simulation results visually show the changes of the meshing characteristics of the cycloidal pin teeth under different working conditions.The rigid-flexible coupling technique is used to extract the continuous node stress curve for analysis,and the position and size of the maximum contact force during meshing are determined,and a theoretical basis for the research and improvement on the way of subsequent shaping is provided.
