Rapid aircraft structure modeling based on structure case base
-
摘要: 为充分利用和借鉴已有的飞机结构件设计方案实例信息,研究了面向对象的参数化结构件实例描述方法,提出了飞机结构件实例库的总体框架并开发了系统的原型.研究了基于实例库的飞机机体结构设计措施及建模方法,提出了翼面结构和机身结构的参数化描述和模型构建方法,并在一个开放式的飞机总体设计环境中完成了基于实例库的飞机结构快速设计功能.最后通过应用示例说明了该系统和方法的有效性.Abstract: In order to utilize and study more effectively from existing examples of aircraft structure information, the parametric object-oriented description method of structure instance was studied. The architecture framework of aircraft structure case base was proposed and the prototype system was established. The design method of aircraft structure based on structure case base was studied. The parametric modeling method of fuselage structure and wing structure was represented. The functionality of rapid aircraft structure design based on structure case base was achieved in an open conceptual aircraft design system.An instance is given to illustrate the effectiveness of the system and methods.
