Abstract: For the realization of the knowledge management and sharing of electric traction shearer parts, the paper analyzes the overall structure and organization of knowledge base and studies the principle and method for building knowledge base. The case base of hierarchy level is built based on the case template foundation theory by the definition and edit of shearer cases. The parametric design method of geometric constraints and engineering constraint are used to build parametric parts library. The material case is built according to the material properties to realize the storage and query of material information. Based on UG platform, the parts knowledge management system of electric traction shearer is developed by using UG secondary development and data base technology. Through the enterprise application, the proposed method improves the design efficiency and provides a knowledge service platform for designers.
