【正文】 the establishment of the inference mechanism to bring puteraided product design. The mechanical system design is mainly based on the characteristics of a product, and design experts in the field of knowledge and experience to push volume and decisionmaking, the pletion of body type, the number of synthesis. To achieve this stage of puteraided design, must study the automatic acquisition of knowledge, expression, integration, coordination, management and use. To this end, the design and scholars at home and abroad program for the mechanical system design knowledge of the automated processing done a lot of research work, the approach can be summarized into the following several. 。s idea of specific described as: In accordance with the appropriate functional structure, seeking to meet the design requirements of the original understanding of the task. The functional structure of the subfunction is performed by the structural elements to achieve, and structural elements of the physical connection between the definition of a feature vector, feature vector and structural elements further the interaction between the formation of the functional diagra m ( mechanical diagram). The program design is based on functional diagram, the first qualitative description of all of the feature vector and structural elements, and then quantitatively describe all the structural elements and the connection parts ( feature vectors), the shape and location to be structure diagram [3]. Roper, H. using graph theory, by means of which he defines as the total design unit (GE), structural elements (KE), functional structural elements (FKE), connect structural elements (VKE), Structural Parts (KT), structure element part (KET) concepts, as well as describe the structure element size, location, and transmission parameters of the interactions between a number of kinds of schematics, the intuitive design professionals have done a formal design method a description of the formation of an effective application of existing knowledge, methods, and applied to ideas and design stage. 7. Bond Graph Method Function of the position of system ponents will be divided into produce energy, consumed energy, changing energy forms, such as various types of energy transfer, and to use bond graphs to express the function ponent solution, hoping to functionbased model and bond graph bine to achieve functional str ucture the automatic generation and functional structure with the bond graph automatic conversion between the search for bond graph generated by a number of design methods. To promote the product on the basis of functional analysis, the product has some features broken down into one or several modular basic structure, by selection and bination of the basic structure of these modular form into different products. These basic structures can be parts, ponents, or even a system. The structure should have a standardized interface (connection and cooperation department), and is serialized, universal, integrated, hierarchical, agile, economicorien
