【正文】 plicable to the function and effects of configuration rules and there is no room for choice, with special requirements, such as ultrasmall machinery, extra large machinery, highvalue functional ponents, and special functional requirements of the parts and so on. Strategy 4: According to the structural design requirements of the solution. The strategy from the existing parts, through different parts of the order and connect to achieve the desired function. matrix design: In the program design process requirementsfunction logic tree (or tree) Description, function of the interaction between, met the requirements of the functional design solution set to provide different design. According the Requestfunctional logic tree requirement function associated matrix, Description to meet the functional requirements for the plex relationship between shows that the functional requirements and the relationship between he gathers. Kotaetal matrix mechanical system as a basis for designing programs, include mechanical systems design space for the functional deposition of space, each of which only said that the design of a module, abstract stage in the senior, Each module movement and a transformation matrix can operate bound vector。s original understanding. graphical modeling method Developed an analysis and design guidance system KALEIT， with a clear level of graphic description of the product structure and the function of the abstract information, the realization of the structure, function graphical modeling, and the functional link between the layers Will be divided into design methods and supporting information exchange 2, Nijssen Information Analysis using methods can be used graphic symbols, with rich semantic model structure, Integration can be described conditions can be classified types of constraints can be achieved between the arbitrary bination of features Will design solutions and information technology integration, and realizing the process of designing different abstraction layers of information between the graphical modeling. idea design Product design into ideas and design stage two. Concept stage of the mission is to find, select and mix design tasks required to meet the original understanding. Design stage of the work is to realize the conceptual stage, the original understanding. The program will be ideas specific description: According to the functional structure suitable for the design tasks required to meet the original understanding. Functional structure of the subfunction by the structural elements to achieve, and structural elements of the physical link between the definition of functional vector function vector and structural elements of the interaction it has developed the functional diagram (mechanical movement schematic). The program design is based on the functional diagram, first of all qualitative description of the functional vector and structural elements further quantitative description of all the structural elements and the Connector (functional vector) the shape and location The structure diagram. Roper, H. Using graph theory, using his definition of total design modules (GE) structural elements (KE), functional elements (FKE), connecting structure elements (VKE) structural ponents (KT), structural elements parts (KET) concept And describes elements of the structure size, location and transmission parameters of the interaction between a number of diagrams, Expert design and intuitive design of a formal description of the formation of the effective application of existing knowledge, will be applied to the concept and design stage. Design methodology from the point of view of the clear mandate of the design work is divided into three steps Design: 1) Access to function and functional structure (referred to as functional)。 Trend INTRODUCTION The rapid scientific and technological development, product performance requirements of the growing number and plexity of increased life expectancy shortened. updating speed. However, the design of the products, especially machinery products in the design means, it appears powerless, lags behind the needs of the times. At present, puteraided product design drawings, design, manufacture and production planning has been the subject of extensive and indepth research and has achieved initial success, and the early stage of product development of puteraided design program is far from meeting the design requirements.
