The architecture of the CAD system of a magnetic bearing is established by using pattern-oriented software architecture. Based on the pipe-filter pattern, all the present resources come from different developing environments, aiding the design of a magnetic bearing system, can be integrated into the system. Replacing the original pipes with database, the concurrent design can be realized in the design process, which changes the serial mode of traditional manufacture. The distributed and heterogeneous design resources can be integrated into the system and shared by importing the broker pattern. Combining pipe-filter pattern with broker pattern, the system is opening and easy to maintain and extend.
