基于MDO方法的卫星集成设计系统分析与实现

Analysis and Implementation of Satellite Integrated Design System Using MDO

为解决多学科设计优化方法中多学科设计、多学科分析、多学科优化过程与卫星总体设计流程集成的问题,采用变复杂度建模技术,并借鉴产品数据管理思想,设计并实现了面向总体设计的卫星集成设计软件系统。阐述了软件的设计思想、系统组成和功能特点,并给出了月球探测卫星概念设计问题的具体应用实例,结果表明软件在解决多学科设计优化方法应用于卫星集成设计问题时的可行性。

It is a challenge to integrate Multidisciphnary Design （MD）, Multidisciplinary Analysis （MA）, Multidisciplinary Optimization （MO） processes with the satellite system design flow. A system-oriented software framework was formulated and implemented for the satellite integrated design by using Variable Complexity Modeling （VCM） method and Production Data Management （PDM） technology. The design conception, structural components and functional characteristics were introduced. Then the software was tested by the example of Lunar Exploration Satellite conceptual design. The results show that it is an effective approach to apply Multidisciplinary Design Optimization （MDO） technology to satellite integrated design.
