一种基于遗传算法的直升机主减速器优化设计方法

行星齿轮减速器具有传动效率高、结构紧凑等优点，在直升机等军用传动系统中得到了广泛的应用。常用的设计方法一般采用惩罚函数辅助方法，这种方法计算量较大且对于多约束备件优势较弱，并且得到的解未必是最优解，因此不利于复杂系统的优化设计。本文首先详细讨论了主减速器的数学模型，接着给出了运用遗传算法求解多约束条件目标规划的详细算法，并根据进化计算得到的最优解与常规的设计方法进行了比较，最后总结出了基于遗传算法的2K-H行星减速器的一般设计方法。

Optimum Design of Helicopter Main Reducer based on Genetic Algorithms

Advantage of planetary gear reducer is high efficiency, tight structure virtue etc, thus it is widely used in military drive system. Traditional design adopts punishment function aided method, while there is a number of calculation work for this method. What's more, it usually can't converge to the global optimum solution, so it makes against complex system optimum design. the main reducer mode is minutely analyzed first and then the corresponding genetic algorithms are presented in detail. Finally, optimum design results are shown and numerical calculation results are satisfactory.
