Abstract: In the process of Internet/Intranet-based optimal design of vehicle brakes, sharing of structural parameters of parts is demanded among the departments of structure design, optimization, robust design, technology, etc. A method of sharing the structural parameters of parts is introduced. It works under the Unigraphics(UG) software. By saving the structural parameters, attribute parameters, technological parameters and standard data into the database, data sharing can be realized through the database server. Users can read and modify these data according to their authority. By performing the two-way drive between the part models and the database, the design result can be reflected in real time throughout the network. This method is based on database technology, UG secondary development technology and ODBC technology and it meets the demands of cooperation among the departments by providing a fast and stable network environment.
