摘要

为了研究设计参数对摆线针轮减速机接触性能的影响,提出了一种适用于各种恢复系数的新型接触碰撞力模型。首先,基于 L-N 非线性接触理论和改进的 Winkler 模型,提出了带有接触深度指数和阻尼的接触力模型。其次,利用赫兹接触理论阐明了在存在间隙的情况下,输出销与摆线轮之间的接触面积、精确位置和相对接触速度。利用改进后的接触力模型和仿真分析,讨论了结构设计参数和工况参数对接触力的影响。最后,以减小接触力和减小减速器体积为目标,采用 NSGA-II 多目标遗传算法构建了减速器结构参数优化模型。结果表明,优化后的结构参数能有效降低输出机构的接触力。

Contact analysis of output mechanism of cycloidal pinwheel reducer
In order to study the effect of design parameters on the contact performance of cycloid reducer, a new contact collision force model applicable to various restitution coefficients is proposed. Firstly, based on the L-N nonlinear contact theory and improved Winkler model, a contact force model with contact depth index and damping was proposed. Secondly, Hertzian contact theory was used to clarify the contact area, precise position and relative contact speed between the output pin and the cycloidal wheel in the presence of a clearance. By using the improved contact force model and simulation analysis, the effects of structural design parameters and working condition parameters on contact force were discussed. Finally, with the goal of reducing the contact force and volume of the reducer, the NSGA-II multi-objective genetic algorithm was used to construct an optimization model for the structural parameters of the reducer. The results show that the optimized structural parameters can effectively reduce the contact force of the output mechanism.
