摘要
提出了一种谐波齿轮传动系统多目标优化设计方法。以啮合侧隙、啮入深度、柔轮疲劳应力为目标函数建立多目标优化模型,将实际系统的相关性能要求范围转化为线性加权法的权系数,并采用了可靠性和速度性较高的增广乘子法进行优化。结果表明,采用此优化方法比分别采用啮合侧隙、啮入深度、柔轮强度等单一优化目标计算得到的综合指标提高了2.9%、6.4%、15.7%。该优化方法可以保证谐波传动获得最佳的传动性能及可靠性,为基于综合工作性能的谐波齿轮传动开发提供了一种新的设计手段。
A multi-object optimal design method was proposed to meet the various performance re- quirements for harmonic drive in different systems, such as harmonic drive precision, load capacity and flexspline fatigue strength in practical engineering. The method established a multi-object optimal model by taking the meshing backlash, engaging depth and flexspline fatigue stress as the object function, and changing the value scope of the relative requirements into the weight of linear weighting method. The results show that the composite indexes obtained from the optimal design method are increased by 2. 9%, 6. 4% and 15. 7% respectively over that of traditional single optimzation object method in meshing backlash,engaging depth and flexspline fatigue stress, The results indicate that the proposed method can define parameters of meshing and design of harmonic drive according to various performance requirements for harmonic drive in different system orders, which makes that the harmonic drive can not only obtain the optimal transmission performance and the better reliability and also carl provide a new design method based on synthetic work performance for development of harmonic drive.
