针对机械产品概念设计中设计知识功能语义定义模糊和隐形知识重用率低的问题，研究了基于领域本体表示的知识库设计方法，支持设计知识的自助发布管理和语义信息检索等功能。提出设计知识表示的本体模式和建模方法，建立领域本体；从概念设计方案需求粒度、功能目标及企业知识自管理等方面考虑，建立多维设计知识分类体系；设计JSON文件到OWL文件的映射规则，实现设计知识的发布、维护、存储和检索。最终实现面向机械产品概念设计的知识管理，为企业设计人员提供知识共享和重用，支持产品概念设计的方案创新。

Since the current mechanical conceptual design oriented knowledge databases lacked of accurate definition of the function and efficient reusing of implicit knowledge, a conceptual design oriented knowledge database based on domain ontology was built, which could provide data operating functions such as self-service application and semantic retrieval. The logical structure and modeling of design knowledge were proposed to build the domain ontology. Multi-dimensional classification schemes of design knowledge were set up considering different granularities and functions of design projects and knowledge managements. The issuing, maintaining, storage and retrieval of design knowledge were realized by conversions of extensible markup languages. With the powerful knowledge management system, designers could reuse and share implicit knowledge efficiently in design activities, which facilitated the innovation of mechanical conceptual design.
