飞机设计域向工装域映射机理研究

Research on Mapping Mechanism from Product Design to Tooling Concept Design for Aircraft

为提高某飞机制造企业产品设计、工艺规划和工装设计的协同设计效率和响应速度,对三者之间的映射机理进行研究。首先依据企业需求,定义飞机设计域、工艺域和工装域的信息构成;然后,明确飞机设计-工艺-工装之间的有机联系,构建基于多色集合理论的分层映射模型,给出映射模型的建模原理和建模流程,从而实现飞机部件从设计特征到工装概念设计特征的映射;最后,开发了相关设计工具并在该公司某机型舱门骨架的装配工艺规划和工装概念设计中进行应用验证,为实现飞机设计-工艺-工装的一体化设计奠定了理论基础和实践基础。

The mechanisms of mapping between product design, process planning, and tooling design are studied to im- prove the efficiency and response speed of aircraft collaborative design for an aircraft manufacturing enterprise. Firstly, ac- cording to enterprise demand, information constitutions of product design domain, process planning domain, and tooling de- sign domain are defined. Secondly, organic connections between the three are built, and a hierarchical mapping model based on polychromatic sets is constructed. Then, the modeling principle and flow of the model are given, thus the mapping in feature from product design to tooling concept design is realized. Finally, related design software is developed and ap- plied to the assembly process planning and tooling concept design of a cabin door frame, which establishes the theoretical and practical foundation for the integration of the three in an aircraft manufacturing enterprise.
