Abstract: To reduce the uncertainty in the current tolerance specification relying on artificial, the ontology-based tolerance specification generated automatically is studied based on automatic generation methodology of assembly tolerance types on ontology. In order to implement this ontology tolerance specification, the related concepts and relationships are analysed and the OWL(Web Ontology Language) is used to code. On the base of the ontology which is implemented, the automatic generation algorithm of tolerance specification is designed, using the SWRL(Semantic Web Rule Language) to define the generating rules. Using this algorithm, the procedure is illustrated by intermediate office propeller shaft of the reducer. The effective ideas and methods will be provided for the study of tolerance specification generated automatically for the CAD system.

摘要: 针对目前公差规范依靠人工指定带来不确定性的问题,在基于本体的公差类型自动生成方法的基础上,研究基于本体的公差规范的自动生成。通过分析公差规范领域知识,提取其中涉及的概念和关系,以此构建公差规范本体,并采用Web本体语言(Web Ontology Language,OWL)编码实现该本体。在所实现本体的基础上,采用语义Web规则语言(Semantic Web Rule Language,SWRL)定义公差规范的生成规则,进而设计公差规范的自动生成算法。应用所设计算法,说明减速器中间传动轴的公差规范自动生成的过程。将为CAD系统中公差规范自动生成的研究提供有效的思路和方法。
