基于知识库的产品辅助设计系统研究

Research on the Product Aided Design System Based on Knowledge Base

文章针对产品设计过程中知识需求多样而利用不足的问题,提出了基于知识库的产品辅助设计系统,并进行了产品设计应用。在此系统中,构建了基于本体知识表示的知识库系统,分析了知识库知识类型和知识访问方法,对如何使用构建的知识库系统进行产品辅助设计进行了总结。最后,以提出的体系框架进行了单筒身管的设计事例,验证了其有效性。

Aiming at the lack use of knowledge for its diverse needs in the process of product design, this paper puts forward a system of product aided design based on knowledge base, as well as carries on the application of product design. In this system, the paper constructs the knowledge base system based on the representation of ontology knowledge, analyzes the knowledge type of knowledge base and knowledge accessing method, and provides the summarization for how to use the knowledge base system for product aided design. Finally, the paper carries on the design case of monocular barrel with the proposed system framework to verify the effectiveness of this method.
