摘　　要：针对产品MBD三维模型PMI标注形式不统一、标注易出错和人工检查难度大等问题,提出了一种基于PMI领域知识图谱的完备性检查技术。该技术采用自顶向下的方法构建了PMI领域知识图谱,利用SWRL规则构建了完备性检查的规则,从标注的冗余关系、标注的取代关系和标注的矛盾性3个方面进行检查,并结合Java Web技术实现了知识推理。最后以船用柴油机的机架为对象,验证了该方法的可行性。该技术极大地缩短了检查时间和降低了设计错误率,提高了工作人员的设计效率。A new completeness checking technique based on PMI domain knowledge map was proposed for solving the problems of non-uniform form of PMI annotation of product MBD 3D model,error-prone annotation,and difficulty of manual checking.The technique uses a top-down approach to construct the PMI domain knowledge map,constructs the rules for completeness checking by using SWRL rules,checks the redundancy relationship of annotation,substitution relationship of annotation,and contradiction of annotation in three aspects,and realizes knowledge reasoning by combining with Java Web technology.Finally,the feasibility of the method was verified by taking the frame of a marine diesel engine as the object.The technique greatly shortens the checking time and reduces design error rate,and improves the design efficiency of the staff.
