航空领域产生的大量历史MBD模型数据,具有很高的重用价值。构建规范化的模型存储数据结构是模型重用中需要解决的首要问题,研究了MBD模型数据的组织形式,以本体技术作为模型类型划分和属性信息的知识表示方法,设计了一种集合几何信息与非几何信息的本体数据结构。基于该数据形式将历史模型数据存储为结构化的本体知识库,通过模型关键信息检索试验验证了该技术的可行性,为海量模型数据重用奠定基础。
A large number of historical MBD model data generated in the aviation field have high reuse value. Construction of standardized data storage model structure is the most important problem that needs to be solved in the model reuse. Studying the organization form of MBD model data, using ontology technology as the knowledge representation of model type classification and attribute information, a set of geometric information and non- Ontology data structure of geometric information. Based on this data form, the historical model data is stored as a structured ontology knowledge base, and the feasibility of this technique is verified through the key information retrieval experiment of the model, which lays the foundation for reusing the massive model data.
