RESEARCH ON CASE-BASED REASONING INTELLIGENT CAD FOR DESIGNING HYDRAULIC CYLINDER

In the conceptual design stage of mechanical product，designers often use some similar cases to help development of products．Based on this feature，this paper presents a case-based reasoning method used for intelligent CAD of hydraulic cylinders，which is represented by case structure and case data，and products are broken down into hierarchical components．Running the prototype system shows that it is an effective approach for CAD system of serial products with minor modifications.
