Abstract: To solve these problems that semantic of information model was simple and information could not be inherited and shared in the process of multidisciplinary design optimization,a modeling method of Diesel Ontology Model for Multidisciplinary Optimization Process (DOMMOP) was proposed.The top-level structure model of diesel ontology and multidisciplinary design optimization ontology was designed,and semantic relationships of modeling objects were analyzed.Aiming at the features of multi-domain large structure of DOMMOP,an algorithm for consistency checking based on Tableau was proposed.To realize the mapping from enterprise product database to DOMMOP,interactive technology based on semantic alignment was proposed,and integration and semantic operation of product database information based on ontology were achieved.To verify the proposed technologies and methods,the multidisciplinary design optimization platform for diesel engine product was designed,on which the application examples of semantic retrieval and semantic driven multidisciplinary optimization were completed.

Key words: diesel engine ontology, semantic alignment, multidisciplinary optimization, consistency checking
