概念机中的结构设计与建模研究

飞机结构设计在飞机研制过程中起着关键的作用,在飞机概念设计阶段进行结构概念设计可以使提出的概念设计方案更加完善。论述了飞机结构设计在概念设计阶段的作用和方法,着重研究了按照面向对象方式进行数据组织的计算机辅助飞机概念设计系统中进行飞机结构概念设计的方法与措施,以及在这一系统中建立结构件数值模型的步骤。结合结构材料数据库的实现,最后提出了集成与结构相关的各种数据库并进行分类管理的建议。

Structure Design and Modeling in Aircraft Conceptual Design Phase

Aircraft structure design plays an importantrole in the whole process of aircraft research and development, and it will make the proposed conceptmore comprehensiveto conduct the structuredesign during aircraft conceptual design phase. This paper describes the importance and methods of structure design in conceptual design. The emphaseswere placed on the methods and measures of conducting conceptual structure design in a computer aided aircraft conceptual designsystem, whose data organizationis object oriented, as well as the process of modeling structure components in this system. Based on the implementation of a material database, it is finally proposed that other relevant databases should be integrated with the design system and managed according to their functions.
