摘要： 机械系统进行结构动态优化设计的最终目标大多归结为对其进行几何形状的优化，在应用极小值原理对机械结构进行三维形状优化设计时，通常须要使用复杂数值方法才能求解，并且求解的过程相当困难。将先进的协同仿真技术作为一种有效求解工具应用到极小值原理的动态优化设计中，实现对不同设计变量的目标函数的求解。以行星框架为例，采用基于接口的协同仿真技术为求解工具，以行星轮数目为参变量，应用极小值原理对行星框架的几何形状进行动态优化设计，对行星框架的疲劳损伤寿命提供量化数据，为对其进行结构改进提供科学理论依据。

Abstract: The ultimate goal of mechanical system’s dynamic optimization design is mainly the structural shape optimization. 3-D dynamic optimism on mechanical structure with principle of minimum is not easy to computer even with the complex numerical method. Therefore, advanced simulation technology is an effective way to achieve the result of target function. As an example, the dynamic optimism of planetary frame is researched with principle of minimum with the number of planetary gears as parametric variable. The results provide not only the quantified data of fatigue life of planetary frame but also the scientific theory basis for the improvement of its structure.

Key words: Collaborative simulation, Dynamic optimization, Planetary frame, Principle of minimum
