摘要

为获得综合性能最优的摆线轮齿廓,提出了一种摆线轮齿廓修形多目标优化设计方法。介绍了摆线轮的齿廓方程和修形理论,进行了摆线轮齿面接触力理论计算,建立了综合考虑摆线轮啮合特性和齿面接触力的双目标优化模型,采用NSGA-Ⅱ算法进行多目标优化求解,并与单目标修形方法进行对比。研究结果表明,相比于摆线轮齿面接触力最小的优化方法,该方法与转角修形齿廓的拟合度提高了3. 99倍;相对于与转角修形齿廓拟合度最高的优化方法,该方法的齿面接触力减少了4. 98%,实现了摆线轮多目标综合最优,证明了该方法的可行性和优越性。

Abstract

In order to obtain the best overall performance of cycloid profile,a multi-objective optimal design method of cycloid gear profile modification is presented. The cycloidal gear tooth profile equation and modification theory are introduced. The contact force of the cycloidal gear tooth surface is calculated. A multiobjective optimization model with considering the meshing characteristics of the cycloidal gear and the contact force of the tooth surface is established. The NSGA-Ⅱ algorithm is used to solve the multi-objective optimal problem,and compared with the optimal method of the least contact force of the tooth surface of the cycloidal gear. The results indicate that the fitting degree of this method and the angle modification tooth profile is improved by 3. 99 times,compared with the optimization method with the highest degree of fitting to the angle modification tooth profile,the contact force of the tooth surface of the method is reduced by 4. 98%. The multi-objective synthesis optimum of cycloid is achieved,and the feasibility and superiority of this method is proved.
