Computer Aided Industrial Design System is a key component of the product digital design platform. It is equally important to control its design process and manage its data and documents effectively to share the data generated in the whole design process. Based on the analysis of the basic functions of the product digital industrial design platform, this paper presents the general model and function frame of product data management system oriented to computer aided industrial design according to its data composition character, integrative method of application software and industrial design flow in the process of computer aided industrial design. In addition, with the industrial design of the pneumatic tools as the object, this paper presents the product data management system to achieve the system integration of computer aided industrial design, 3-D structure design and CAE analysis and the data share.
