摘要

为了提高安全性能和实现轻量化要求,对某航空多支路分流传动系统进行了多目标优化设计。选取传动系统参数为设计变量,通过计算齿轮接触和弯曲疲劳强度来衡量系统的安全性,建立了以系统质量和总安全系数为目标函数的多目标优化模型。优化模型中考虑分流传动系统对均载性能的要求,建立了多支路分流传动系统的动力学模型,计算得到系统的均载系数并对其进行约束。采用非支配排序遗传算法II（NSGA-II）求解优化模型,结果表明:给出的某航空多支路分流传动系统多目标优化设计方法能够提高系统安全性,实现轻量化。

Abstract

The promoting the safety performance and lightweight are considered as the objectives,a multi-objective optimization design of an aviation split path transmission system is conducted.To measure the safety performance of the system,gear contact and bending fatigue strength are computed.Afterwards,a multi-objective optimization model that includes maximum safety factors and minimum mass is developed,with the system parameters selected as design variables.Considering the system requirements for load sharing,a dynamics model of the split path transmission system is established so that the load sharing characteristics can be quantifiably measured and restricted.Non-dominated Sorting Genetic Algorithm II（NSGA-II）is adopted to solve the model.The results show that the method promoted can effectively improve the safety performance and reduce the weight at the same time.
