当前的产品信息模型缺乏一致、统一的表达,尤其是语义信息没有得到全面的描述,不能满足不同设计者对产品信息模型的不同需要,另外,产品信息模型也不能描述功能信息,针对这些缺点,提出了利用本体思想从功能层、原理层和结构层3个层面来描述产品信息模型,通过本体构建软件protégé建立液压支架产品的控制本体、结构本体及架型本体等子本体,最终集成为液压支架产品的本体模型。该模型可为后续的液压支架的检索与重用等提供基础模型,更好地辅助设计人员进行产品开发,从而缩短产品开发周期。通过基于本体的液压支架产品信息建模的研究,验证了多视图产品信息建模方法的可行性,并为基于本体的产品信息描述提供借鉴的方法和经验。
The current product information model lacks a consistent and unified expression. In particular, the semantic information is not fully described and can not meet the different needs of different designers for the product information model. In addition, the product information model can not describe the function information. In view of these shortcomings, This paper proposes the idea of ontology to describe the product information model from the functional level, principle level and structure level. The main body of the hydraulic support product, such as control body, structure body and frame body, is built by ontology building software protégé. Finally, Bracket product ontology model. The model can provide a basic model for the subsequent retrieval and reuse of hydraulic supports to better assist designers in product development, thus shortening the product development cycle. Through the research of product information modeling based on ontology hydraulic support, the feasibility of multi-view product information modeling method is verified and the method and experience of using product information description based on ontology are provided.
