Optimal Design of Automotive Brake System Based on Product Data Management System

Using B/S mode,a network-based design platform for the vehicle brake system is constructed based on product data management(PDM) system.The collaborative management and data sharing in the whole design process are realized by applying the techniques of version control and work flow management in the PDM system.By means of the self-parsing and self-updating of design knowledge,the design parameters matching and the data sharing for designing the like product,the intelligent and automatic design process is realized. The update and maintenance of the design algorithm and the strategy for realizing the automatic expansion of case-based knowledge are emphatically studied.Hence the difficult problems of self-updating and self-learning of knowledge are systematically solved.
