摘　　要：飞机机电作动器(EMA)要求可靠性高和使用寿命长,其行星轮减速器设计变量多,计算复杂,一些重要参数的选取直接影响EMA性能及使用寿命。为得到能够显著提高EMA性能的小体积行星轮减速器,采用设计空间缩减多学科协同优化设计算法对行星轮减速器进行研究。首先建立了由1个目标函数、5个设计变量和8个约束方程构成的优化设计模型,然后进行设计计算和优化结果分析。结果表明,优化设计的数学模型能够真实反映设计问题,优化结果切合实际,准确可靠。Aircraft electro-mechanical actuator （EMA） has a need for high reliability and long service life. There are many variables in the design of planetary gear reducer and the calculation progress is complicated. Some important structural parameters have a direct influence on the performance and service life of the electro-mechanical actuator. In order to obtain a small planetary gear reducer that can significantly improve the performance of electro-mechanical actuator, this paper uses the design space decrease collaborative optimization to make a research on the optimization design of planetary gear reducer. Firstly, an optimal design model composed of one objective function, five design variables and eight restrictions is established, and then the design calculation and optimization result analysis are carried out through the design space decrease collaborative optimization algorithm. The results show that the optimization design model of the planetary gear reducer can reflect the design problem, and the optimization result is practical, accurate and reliable.
