摘    要:为了减少机械产品设计过程中的不确定性,解决装配公差信息在异构CAX系统中共享性差和传递不畅的问题,利用本体丰富的语义知识和语法结构,通过分析装配公差综合领域相关知识,采用网络本体语言OWL定义其中的概念和关系,并采用语义网规则语言SWRL定义其中的约束条件和分配经验。将基于OWL的结构化知识转换成事实、基于SWRL的约束化知识转换成规则,并在推理引擎的基础上构建装配公差综合领域本体知识库。同时开发了基于本体的装配公差综合原型系统,实现了装配公差类型和装配公差值的自动生成。

关 键 词:公差综合  本体  知识库  自动生成

Abstract:To reduce the uncertainty in mechanical product design and to solve the problem of effective sharing and smooth transferring of assembly tolerance information among heterogeneous CAX systems, we construct an ontology knowledge base for the assembly tolerance synthesis. We first analyze the assembly tolerance knowledge based on the ontology that contains abundant semantic knowledge and semantic structures. The web ontology language (OWL) is used to define the concepts and relations, and the semantic web rule language (SWR) is used to define the constraint conditions and distribution experience. Afterwards, the OWL-based structure knowledge is mapped to facts, the SWRL-based constraint knowledge is mapped to rules, and an ontology knowledge base for the assembly tolerance synthesis is constructed based on the inference engine. Meanwhile a prototype system of the assembly tolerance synthesis is developed based on the ontology, which can automatically generate the assembly tolerance types and assembly tolerance values.
Keywords:tolerance synthesis  ontology  knowledge base  automatic generation
