摘要: 为解决飞行器总体设计的难点,介绍了可用于飞行器多学科设计优化的软件.该软件利用"松耦合"方式,以SQL Server 2000为数据库管理系统(DBMS),与各学科分析程序相结合.阐述了该系统的功能和软件结构、软件流程、主要模块.为解决关键技术,提出圆环图处理总体与各学科的关系,利用模糊理论进行非数值型变量的转化,提出无量纲化多目标法进行多目标综合处理,构建单一数据库进行数据管理,采用三个数据文件作为程序接口.总结了软件的特点.算例表明软件具有实用性.Abstract: In order to solve difficulties of flight vehicles overall design, a software for flight vehicles multidisciplinary design optimization was introduced. Which adopts a "loose coupling" algorithm, uses SQL Server 2000 as its data base management system(DBMS), and combines with various analytical programs of disciplines. The system function, software structure, software process and main modules were discussed. To deal with critical techniques, the ring-shaped graphical was put forward to deal with the relationship between overall and disciplines, the system fuzzy theory was adopted to transform non-numerical variables, the non-dimensional multi-object method was presented to solve multi-object, a single database was built to perform data management, and three data files were applied to program interface. The features of software were concluded. The calculation result shows that the software works effective.
