In this paper a method is proposed, that is used in Simulation Data Management and Simulation Process Control related to mechanical product design and analysis process. Based on the MSC.SimManager developing environment, the database schema and general data model between the product design and analysis process is designed according to the requirement of the. product design and analysis; the Simulation Process Control is achieved through the integrating the CAD redevelopment with CAE redevelopment and the XML technology, the results and interface data between design and analysis software is also managed efficiently. Meanwhile, the multi-user interactive collaborative design environment is implemented by taking advantage of the LAN technology.
