摘　　要：摆线针轮是RV减速器中主要组成部分之一,为了进一步提高RV减速器的承载性能,提出了一种以摆线针轮接触应力、啮合刚度为优化目标函数的多目标优化设计方法。为了优化其承载性能,以针齿分布圆半径、短幅系数、针径系数、摆线轮宽度为设计变量,构建了接触应力最小、啮合刚度最大的优化数学模型,使用Matlab调用其优化工具箱中的遗传算法进行了求解。优化设计后的结构与原结构相比较,接触应力减小,啮合刚度增大,摆线针轮的承载性能获得改善。研究为RV减速器的设计提供了一种新的方法。Cycloidal pin wheel is the main component of RV reducer.In order to further improve the load capacity of RV reducer,a multi-objective optimization design method based on cycloid pinwheel contact stress and meshing stiffness is proposed.In order to optimize its load capacity,an optimization mathematical model with the minimum contact stress and the maximum meshing stiffness is constructed by taking the pin tooth distri⁃bution circle radius,short amplitude coefficient,pin diameter coefficient and cycloidal wheel width as design variables.Matlab is used to call the genetic algorithm in its optimization toolbox for solution.Compared with the original structure,the optimized structure reduces the contact stress,increases the meshing stiffness and im⁃proves the bearing performance,which provides a new method for the design of RV reducer.
