摘　　要：为实现公差与配合选择的智能化,减少公差与配合选择过程中隐含的经验化知识带来的不确定性,将本体技术引入到公差与配合的选择中。首先,从公差与配合的选择过程出发,构建相应的公差与配合表示模型,并使用网络本体语言OWL2表示模型中各层次之间的配合关系。其次,基于所构建的表示模型,以本体推理规则的形式显示地构建公差与配合信息本体。然后,运用语义网规则语言SWRL定义公差与配合选择的推理规则。通过本体编辑工具protégé中的推理引擎得到最合理的公差与配合。最后,通过工程实例展示该方法的工作过程,并验证了方法的有效性。In order to realize the intelligent selection of tolerance and fit,and reduce the uncertainty of the implied and empirical knowledge in the choice of tolerance and fit,ontology technology is introduced into the choice of tolerance and fit.Firstly,starting from the selection process of tolerance and fit,the corresponding tolerance and fit model is constructed,and the OWL2(Web Ontology Language 2)is used to represent the fit relationship between the various levels in the tolerance and fit model.Secondly,based on the established representation model,the tolerance and fit information ontology are constructed obviously in the form of ontology inference rules.Then,using the SWRL(Semantic Web Rule Language)to define the inference rules for the selection of tolerance and fit.The most reasonable tolerance and fit are obtained through inference engine in the ontology editing tool named protégé.Finally,the working process of the method is demonstrated by an engineering example,and its effectiveness is verified.
