航天器结构总体评价与建模

The Assessment and Modeling for the Spacecraft Structures

随着计算机技术与航天技术的不断发展,一方面要求航天装备所完成的任务越来越复杂、体系越来越庞大;另一方面,对航天装备系统的设计也要求更安全、更经济和更可靠.应用现代计算机辅助设计技术,从系统和总体角度对航天装备体系方案进行快速分析与评价,给出优化的体系结构,具有较大的实际意义;对常用的几类航天器结构进行比较、分类,研究了总体评价参数、设计载荷、模型等;给出了相应的软件设计框架,为建立航天器结构快速评价系统奠定了基础.

Along with the continuous progress in calculator technique and space technology, on the one hand, the mission of space equipment systems is more complicated, and the system is bigger. On the other hand, the system design of the space equipment is also requested safer, more economic and more reliable. From the system and the collectivity viewpoint and to adopt the modern CAD technique, rapidly analyzing and evaluating a space equipment system and getting the optimized structures has a higher actual significant. The common used types of spacecraft structures have been compared, classified and the total assessment parameters, design loads, evaluation model and application examples have been researched in this paper. The software framework for evaluating space equipment system has been given. It establishes the foundation for the fast evaluating space equipment system.
