基于知识的飞机制造协调路线交互设计技术

飞机制造协调路线是一种重要的工艺文件,是联系互换协调方案制订和容差分配的纽带。飞机制造协调路线的数字化设计对于开展计算机辅助容差设计,以及实施飞机数字化工艺具有重要意义。首先,对飞机制造协调路线的设计知识进行分类,建立其知识表示模型,并运用知识推理技术实现知识的应用。其次,建立了制造协调单元的图符库,运用图符智能捕捉技术辅助制造协调路线的交互式创建。最后,建立了飞机制造协调路线信息模型,进而实现了面向容差分配的规范化尺寸协调工艺文件自动生成,为计算机辅助容差设计提供技术支持。

Interaction Design Technology of Knowledge-Based Aircraft Manufacturing Coordination Route

Aircraft manufacturing coordination route is an important process file,which connects the interchangeable coordination scheme designing with tolerance distribution.The digital design of aircraft manufacturing coordination route has important significance for computer aided tolerance design and the implementation of aircraft digital process.First,we classify the design knowledge of aircraft manufacturing coordination route and build the knowledge representation model and use the knowledge by reasoning technology.Then,we create figures library of manufacturing coordination units and design manufacturing coordination route interactively using intelligence capturing technology.Finally,the information model of aircraft manufacturing coordination route is designed and coordination process files for the standardization of the tolerance allocation are generated automatically,which provide support for the computer aided tolerance design.
