支持产品创新的机电领域知识库构建技术研究

摘要

How to make use of domain knowledge to help designers with innovation process has become the focus of current research. A technology of constructing domain knowledge base supporting electromechanical product innovation is put forward, acquisition method is built according to electromechanical domain knowl-edge features, electromechanical domain knowledge base is built using ontology offering three retrieval ways that are key words, natural semantic and function, meanwhile the example of machine tool's overheating protection is used to show knowledge base supporting innovation design.%如何发挥领域知识在产品设计中的作用，辅助设计人员实现产品创新过程是当前研究的热点。文章提出了一种支持机电产品创新的领域知识库构建技术，根据机电领域知识特点建立知识获取方式，利用本体技术对机电领域知识进行本体构建，提供基于关键词、自然语义及功能三种检索方式，建立了支持产品创新的机电领域知识库，并结合机床电机过热保护这一示例展示领域知识对产品创新设计的支持。
