| 摘 要： | 微小卫星总体设计是多学科权衡和优化的过程,需充分考虑各个学科之间的耦合关系、搭建有效的设计环境,以实现整体性能指标优化。该文研究了多学科设计优化(multidisciplinary design optimization,MDO)构架,开发了相应的飞行器分布式设计环境(spaceraft distributed design environment,SDIDE)。这是一种基于协作优化方法和分布式对象技术的卫星总体MDO并行设计构架。在清华大学NS-1卫星的构型设计优化实例中,应用SDIDE以合理的温度场分布为目标进行优化设计,取得了理想结果,验证了该设计构架应用于卫星总体设计问题的可行性和实用性。

| Abstract: | The overall design of a micro-satellite is a process of multidisciplinary balance and optimization.Therefore,taking the interdisciplinary coupling into account and creating an effective design environment is needed to achieve the overall performance optimization.The multidisciplinary design optimization(MDO) framework was analyzed to develop the spacecraft distributed design environment(SDIDE) which is an concurrent satellite MDO framework based on collaborative optimization and distributed object technolog... |
