A knowledge-based approach for the task implementation in mechanical product design

摘要

Although advances have been made to integrate the CAD system with design knowledge, there are still some barriers to apply the knowledge-based design approach to wide practice. A task implementation method is proposed for the mechanical product design process. The design task implementation model is constructed based on its organized-mode and modularity. Declarative knowledge primitives make up of the kernel composition of design task. It makes the design task more controllable and automatable. Solution of the knowledge primitives is directly used to drive the mechanical product. The proposed module has been developed for Intesolid2.0 system, a mechanical CAD system, and it has been evaluated with a design example of a two-stage gearbox.
