集成仿真在空间望远镜设计和优化中的应用

Application of Integrated Simulation in Design and Optimization of Space Telescope

针对空间望远镜设计过程中涉及学科多、系统复杂、真实环境验证难度大等特点,集成仿真在空间望远镜设计和优化过程中具有巨大应用价值。本文给出了集成仿真在NGST、NEXUS和JWST等空间望远镜设计过程中的应用实例,介绍了集成仿真所包括的扰动源、结构、光学、控制和模型集成等方面的具体内容,并给出了集成仿真在性能分析、灵敏度分析、同效性分析、多目标优化和干扰来源定位与缓解等方面的应用。集成仿真技术及其应用案例,对我国在研大型空间望远镜的设计有指导和借鉴意义。

Considering the characteristics of the space telescope design such as multidisciplinarity, complexity and difficulty of physical test, integrated simulation can play an important role in the design and optimization process of a space telescope. Application of integrated simulation in the design process of space telescopes such as NGST, NEXUS and JWST was presented in this paper. Integrated simulation included disturbance, structure, optics, control and model integration. Integrated simulation could be used for performance analysis, sensitivity analysis, isoperformance analysis, multiobjective optimization, disturbance location and reduction. Integrated simulation and its applications provide guidance and reference for the design of large space telescopes in China.
