Abstract: In view of generalized modular design theory, the concept of flexible general framework is put forward as to satisfy design requirements of various products. By separating commonness and individuality in the process of modularization, the structure system of this framework is set up, which involves some key technologies, including integration among multi software systems, coding for products and modules, and modeling for universal information. On the basis of this framework, taken hydraulic pressure product as an example, its products family and modules are able to be planed; then the product information model will be established. So the possibility of parameterizing and variablizing the design of this kind of product can be realized, meanwhile the integration of CAMD/CAE/ CAP is achieved. Consequently, the rapid design and pricing for hydraulic pressure can be successfully carried out.
