基于本体的产品设计知识表示方法

摘要

针对产品设计知识的多样性、动态化和相关性等特点,提出了一种基于本体的产品设计知识表示方法.建立了以客体、概念集、属性集、命题集和函数集为核心的知识单元,并设计了五者之间的联系,在此基础上引入了输入输出模块,以增强产品设计知识表示的全面性和灵活性.最后以圆柱形螺旋弹簧设计为例,验证了所提方法的有效性.%According to the diversity, dynamics and correlation of product design knowledge, this paper put forward a knowledge representation method for product design based on ontology, established a knowledge unit with the core of object, concept set, property set, proposition set and function set, and designed the links between them. On this basis, this paper introduced input and output modules to enhance the comprehensiveness and flexibility of product design knowledge representation. Finally, the paper took cylindrical spiral spring design as an example and verified the effectiveness of the proposed method.
