Digital industrial design system combines the digital technology and industrial design process，and integrates the sub-systems of digital modeling, digital assemble, digital evaluation, digital manufacture, and digital information exchange. In order to let the industrial design work process and the design data flowing fluently around such sub-systems, Product Data Management (PDM) system is introduced here as the basic integration platform of the sub-systems to let the design process flow and design data flow working well. The product digital industrial design platform basic functions and its system structure is analyzed, and a general model and function frame of product data management system oriented to digital industrial design is presented in this paper to solve its characteristic data composition, integrative method of application software and industrial design flow in the process of the digital industrial design. Results about the working process integrative model, control process model, product class definition model, and the logical structure of the digital industrial design platform with the PDM system are also established. An application results for certain product development show that such digital industry design system can make the helps for the design work efficiency and the follow-up engineering design accuracy.
