协作优化算法在飞行器设计中的应用

Collaborative Optimization and its Application in the Design of Space Vehicle

协作优化算法是近年来兴起的一种多学科优化算法,该方法通过分解、协调的方式解决飞行器设计中多个学科的耦合和数据关系复杂的问题。文中首先分析了协作优化算法的基本构架和数学表达形式,通过改变系统级等式约束,使协作优化算法的计算特性大大改进。最后讨论了这种算法在飞行器优化设计领域中的应用,并给出了一个计算实例。

Collaborative Optimization (CO) is one of multidisciplinary design optimization methods developing rapidly since last decade,in which decomposition and coordination are used to solve the multidisciplinary coupling and complication.In this paper,the framework and mathematical expression of CO is presented and analyzed.The computation capability of CO is improved remarkably through modifying system-level equation constraints.The application of this method in the design optimization of space vehicle is discussed and a practical example is presented.
