Abstract
Considering the characteristic of composite component design, a knowledge-based system for the design of aircraft composite component is developed. The system design adopts client/application/server (C/A/S) three-layer structure. The implementation method and theory of the knowledge-based system is introduced in detail. Firstly, the system architecture of the developed knowledge-based system is presented. Then, the system framework of the case design base is also described. Case design of a composite component includes question description and solving scheme of this component. By comparing the question description and calculating the similarity of the components, new case design can be obtained from the existed case design. This knowledge-base system is integrated with CATIA software. The process of data exchange between CATIA and knowledge-base system is presented. The 3D model of composite component created in knowledge-base system can be modified by parameter driving. By implementing the proposed knowledge-based system, the design efficiency of composite component can be increased.
