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.
In order to make full use of and learn from the existing example information of aircraft structural parts, the object-oriented description method of parametric structural parts is studied, the general framework of the aircraft structural parts instance library is proposed and the prototype of the system is developed, Library aircraft body structure design measures and modeling methods proposed airfoil structure and the fuselage structure of the parametric description and model building method and completed in an open aircraft design environment based on the case base of the aircraft structure quickly Design function.At last, the effectiveness of this system and method is illustrated through application examples.
