Abstract：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.
