A Knowledge Reuse Method for Product Design-knowledge Component

In order to promote the reuse of product design knowledge in product design and improve the efficiency of product design, the paper analyzes the structure of knowledge components, proposes the framework of product design system based on knowledge component, and studies the design and implementation of knowledge component combined with computer component technology. The barrel product is selected as the research object, of which the knowledge components are built. Then the paper designs and develops the design system based on knowledge component of the barrel. It proves the method based on knowledge component can effectively realize the reuse of product design knowledge. However, the developed knowledge components have certain limitations, which are only applicable to the same products or similar products. The generality of the knowledge components, the portability of the system and the migration of knowledge still need to be further verified.
