摘　　要：在复杂机械产品设计过程中,针对知识模型存在的语义阐述完整性和可拓展性问题,对面向智能化设计的复杂机械产品知识建模进行了研究,提出了一种改进的复杂机械产品可拓本体模型。该模型在经典本体模型的基础上,融合可拓理论,对可拓本体概念、可拓本体相关定义以及可拓本体定理进行了拓展,给出了可拓本体模型建立的相关原则,提出了复杂机械产品可拓本体模型建立的具体实施步骤;最后,以某型号直升机为应用实例,对复杂机械产品可拓本体模型建立过程进行了验证分析。研究结果表明:所提出的可拓本体模型具有较好的完备性和可拓展性,能够对复杂机械产品智能化设计的顺利实施提供支撑作用。Aiming at the problems of completeness and scalability of the semantic model in the design of complex mechanical products,knowledge modeling of intelligent design of complex mechanical products was studied and analyzed,and an improved ontology model of complex mechanical products was proposed.Extension theory and classical ontology model were integrated into this model.The concept of extension ontology,the definition of extension ontology,and the extension ontology theorem were extended.The related principles of extension ontology model were given.The specific implementation steps of ontology model establishment were proposed.Finally,a certain type of helicopter was taken as an example,and the extension ontology model establishment process of complex mechanical products was verified and analyzed.The results indicate that the extension ontology model proposed has good completeness and expansibility,which can provide support for the intelligent design of complex mechanical products.
