摘　　要：采用本体化知识库开发方法与技术,构建了高速旋转机械转子轴承系统协同设计知识库,并对其功能进行了验证.利用Protégé本体开发平台,对高速旋转机械转子轴承系统多学科设计知识进行了本体论建模,并开发了采用OWL语言描述的设计知识本体库.采用Jena技术框架,通过本体库与知识库的映射,完成了该类复杂产品协同设计知识库的建设.以两跨转子轴承试验台的设计作为工程应用案例,通过实现设计知识共享、重用和异构系统的互操作,对知识库原型系统的摩擦学设计模块、仿真及试验数据协同分析模块的功能进行了验证,验证结果表明,基于本体理论构建的知识库可有效服务于复杂产品的协同设计.A high speed rotary machine rotor-bearing system collaborative design knowledge repository is constructed by ontological method and technology,and the functions of knowledge base prototype system are verified.The ontological models are made for multi-disciplinary field design knowledge of high speed rotary machine rotor-bearing system and ontology web language format design knowledge ontology repository is developed based on protégé ontology development platform.Then the complex product collaborative design knowledge repository is established with Jena technical framework,by mapping and data transferring from ontology repository to knowledge repository.Taking with the design of two-span rotor test-bed as an engineering example,the knowledge repository prototype system functions of tribology design and collaborative analysis module of simulated and experimental data are verified by implementing knowledge sharing,reuse and interoperability of heterogeneous system.
