To solve the problems of low inheritance and reuse rate of the design experience and knowledge of the Fuze mechanism,the expert system technology based on knowledge engineering,the simulation process and parametric technique are introduced in the design process of fuze mechanism,to improve the quality of product,shorten the design cycle and reduce the cost. The intelligent design system of the fuze mechanism uses different methods of knowledge representation to meets the design requirements of the case from the knowledge base through the mixed reasoning method of cases and rules. The finite element analysis and parametric design are realized by using the simulation module and model base module of the system. The test of the system shows that the intelligent design system can achieve the reuse of knowledge and experience effectively.
