Abstract: For the problem of that the various design knowledges of self-propelled artillery have not been organized and represented effectively and the existing design knowledge cannot be reused simply during the design process, a knowledge representation method is proposed based on ontology and knowledge components. The organization mode for design ontology of self-propelled artillery and the developing strategy for knowledge components are studied on the base of analyzing the representation requirement of design knowledge of self-propelled artillery, and the mapping relationships among design ontology and knowledge components are established. The representation of design knowledge of self-propelled artillery is achieved. On this basis,a special knowledge retrieval system is developed for designers to quickly reuse the existing design knowledge. The representation and reuse of design knowledge are implemented by taking large-caliber self-propelled artillery for example. The result shows that the proposed method is feasible and valid.
