摘要: 为提升现有CAD(Computer-Aided Design)系统对设计知识的重用能力,提出 了设计知识的分层描述和集成建模方案,并给出了具体实施方法.将设计知识划分到构型层 、设计层和造型层3个抽象层次,基于UG(Unigraphics)平台的知识熔接语言(KFL,Knowl edge Fusion Language)和Open++实现了各层设计知识的描述与集成.构建了知识集成模型 的创建和重用支撑系统框架.作为应用实例,在UG平台上开发了专用减速器快速设计系统.

Abstract: The approach to improve the existing CAD(Computer-aided design) system s′ capacity in design knowledge reuse was discussed. The scheme and implementat i on approach of representing hierarchical knowledge and constructing integrated k nowledge model were proposed. Design knowledge was divided into three abstract l ayers: configuration layer, design layer and modeling layer. KFL(knowledge f usion language) and Open+ + of UG(Unigraphics) were adopted to represent and inte grate design knowledge in the three layers. A system frame supporting the genera tion and reuse of integrated knowledge model was designed. And the application o f the frame was illustrated by a system for the special retarder rapid design.
