面向重用的MBD模型本体知识库构建技术研究

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。

Research on Construct Technology of MBD Model Ontology Knowledge Base oriented to Reuse

There are many history MBD models in aviation enterprises,which have great reuse value.It is the key problem to construct normalized model storage data structure in model reuse,we researched on the organizational form of MBD model data,used ontology technology as knowledge expression form of model type division and attribute information,designed ontology data structure including both geometry and non-geometry information.Based on this kind of data form,We transform history model data into structural ontology knowledge base and verify technical feasibility by retrieval of model key information,make preparation for magnanimity model data reuse.
