Title  The Development of Component Design Application System 

Abstract

In the product design, the acquisition, transfer and use of knowledge of the design process has become the key factor to succeed product market. Therefore, the supply efficiency of the knowledge for design personnel's plays a key role to the overall success in the product design, so it must provide enough knowledge to support design decisions in the design process. 

Firstly, through literature research on product design system, and analyses the present research situation and development trend of product design system, and simply introduces the research status of knowledge engineering at home and abroad. Then, studied in product design concepts, theory and technology, starting from the definition of the product design, analyzes the knowledge classification of the product design, knowledge acquisition of the product design, and process of the product design; introduces the concept of product scheme design and parameterized design briefly. To design the recuperator scheme as an example, and analyzes the product design based on knowledge engineering and the method of parametric design based on the examples, analyze the needs of the recuperator design and the design of the database and the matching process of the similar case retrieval. Finally, on the basis of the above research, developed the prototype system for the design of the recuperator scheme, and prove the implementation of main modules of the system and its key technologies and  application of prototype system verifies the effectiveness of the method of product design.
