【Abstract】 Modular design is one of the key techniques to achieve product diversificationand rapid design, which theory and methods are being developed and amended. For akind of product, a adaptive design method should be researched.Through analyse of current product design and structure of flyer frame, thisdissertation puts forward product platform-based generalized modular design, whichcan implement product variety, also realize economics of scale. This thesis can bedivided into six chapters. The following is the abstract of each chapter.In chapter one, the modular design concept, meaning are introduced. Andcontents about identification and assemblage of module, layout of modular productfamily and product platform are emphasized, theory study and application of whichare summarized.Chapter two presents the theory of product platform-based generalized modulardesign, and studies the types and layout ways of modular product platform. And theprocess model of product platform-based generalized modular product design is given,and each step of the model is explained in detail. At last, the build principles ofmodular product platform are illuminated.The third chapter studies the techniques of flyer frame modular design. And theheuristic means of product function module identification is given. By this way thefunction module of flyer frame is created. Then the establishment of product platformof A456 flyer frame family is researched.The build theory based on similar feature converged of generalized module isbrought forward in chapter four, and the sample of feeding generalized module offlyer frame is presented. Based on this, the parameterized model of generalizedmodule is made, and the way of module customization according to the generalizedmodule model is illuminated. Also the process of product customization based onproduct platform is explained.Chapter five addresses the data model of flyer frame in the generalized modular designsystem. And the hiberarchy model of flyer frame product family is given, by whichthe uniform data model is made. Then the knowledge representation of generalizedmodule is studied, and the frame description model of flyer frame is built.In the last chapter, a computer-aided flyer frame generalized modular designsystem is founded, and its structure, function, work flow is illustrated. Some designexample of the system are introduced.更多还原
