摘 要:
根据月球探测卫星任务及环境的特点，在将多学科设计优化（MDO）方法用于卫星总体概念阶段的设计。分析了卫星总体设计中轨道设计、卫星设计和发射选择间的耦舍关系与协同效应，建立了MDO的简化模型。用单级整体优化策略（AAO）和多岛遗传算法（MIGA）进行优化。算例结果表明，MDO简化模型可有效解决卫星概念设计阶段中的多学科耦合。[著者文摘]

Abstract:
Multidisciplinary design optimization （MDO） was used in conceptual system design for lunar exploration satellite according to the task and characteristics of the lunar .satellite in this paper. The coupling relationship and associated effect among orbit design, satellite design and launch determination in the satellite system design were analyzed, and the simplified MDO module was founded. The methods of all-at-once and multi-island genetic algorithm were used to optimize the module. The computation results showed that the simplified MDO could implement the muhidisciplinary decoupling in the conceptual design for satellite,[著者文摘]
