    摘要:

    虽然RV减速器具有体积小、重量轻、传动平稳、寿命长、传动效率高等一系列优点,但是摆线盘和针齿啮合时的接触应力比较大,磨损情况严重。为了优化结构的接触特性以及质量,以针轮的分布圆半径、短幅系数、针齿半径、摆线盘厚度为优化变量,分别以最大接触应力、质量最小化为优化目标,分别采用遗传算法和fmincon非线性优化方法进行优化。两种优化方法得到的结果比较一致,且都有比较明显的优化效果,但是造成另外一个优化目标的增大。为了使两个优化目标都得到比较良好的优化效果,采用fgoalattain多目标算法进行多目标优化。

    Abstract:

    Although the RV reducer has a series of advantages,such as small size, light weight, stable transmission, long life and high transmission efficiency, but the contact stress between the cycloid and the gear teeth is relatively large and the wear is serious. In order to optimize the structure, the maximum contact stress and the quality is considered as the goal of optimization to reach a small magnitude, with the distribution radius of wheel, short width coefficient, radius of the pin wheel, thickness of cycloid pin gear as optimization variable. Two methods, the genetic algorithm and fmincon nonlinear optimization method, are used. The results obtained by the two optimization methods are consistent, and both have obvious optimization effects, but they lead to the increase of another optimization objective. In order to make the two optimization objectives get better optimization results both, fgoalattain multiobjective algorithm is used to optimize the multiobjective.
