摘 要:飞机制造大型工装是保证飞机产品协调互换和几何参数的重要工艺装备,其研制工作量大,周期要求越来越短。目前,中国航空制造企业大型工装设计和制造并行的需求十分迫切,且亟需计算机辅助概念设计工具的支持。为此,对飞机制造大型工装的布局问题进行研究,引入逻辑构件对飞机制造大型工装进行抽象建模,提出了一种依据布局约束要求分级演进求解的布局设计算法,即依次通过定位点级、元件级和工装级骨架轴位域的演进求解获取骨架元件的合理位置,并结合人机域的求解进行工装布局设计。开发了相关布局设计工具,在某型号飞机后机身装配型架设计中应用验证,大大减少了设计迭代和返修率。Large tooling in aircraft manufacture is a mechanical product used to ensure the complex aircraft structure's figure and coordination.The workload of its design and manufacture is huge,and the developing cycle desired becomes shorter and shorter.It is needed urgently to fulfill concurrent design and manufacture for large tooling,and develop computer-aided conceptual design software to support large tooling design as well.In the light of the research on layout design and the large tooling model quoting logical component,a layout design algorithm based on classification and evolution computation according to layout restriction is brought forward.In this algorithm,rational situation of frame element is worked out by evolution computation of anchor-point level,frame element level and tooling level in turn.Computer-aided conceptual design software related is developed and applied to latter-airframe assembly tooling design.It proves less design iteration and lower percentage of tooling sent back.
