【正文】 a puter language to describe the identification and design of products features experts in the field of knowledge and experience, knowledge base and establish the corresponding reasoning machine to use the storage areas have knowledge of the reasoning mechanism and the establishment of the programmer to achieve puterassisted design products. Mechanical systems design of the programmer 5 is based on products of the main features, and design experts in the field of knowledge and experience on the volume and decisionmaking, plete body type, a few integrated. Computeraided design stage to achieve this, we must study the automatic acquisition of knowledge, expression, integration, coordination, management and use. To this end, and scholars in mechanical systems design knowledge of programmed design automated processing done a lot of research work, the methods used can be summarized in the following few. Coding method According to motion transform (called functional element) the anization classified, and use codes to describe the types of institutions and function element, which has led to the establishment of body system programmer design expert systems knowledge base. On this basis, binary logic of bining theory with vague integrated judge the establishment of the expert system reasoning mechanisms, and dedicated spaces for the four programmers designed machine tools. Use of biological evolutionary theory, through natural selection and sexual reproduction to enable anisms to the principles of evolution, in programmed design agencies, the use of work theory approach will map the structure of institutions for topography expression, and through the coding technology, the body structure and functions into individual chromosome number string of binary system, and prepared in accordance with design requirements to value use of biological evolution theory breeding control mechanism through selection, overlapping and sudden variations, and other means to eliminate low valuenot to be very adaptive in the evolutionary process of the individual optimal, the best design for the agency. design catalogue method Construction of the functional modules, functional element and body group progressionstyle design catalogue, and this threetiered progression of the design principles of the programmed catalogue as a mechanical transmission systems design knowledge base and the development of intelligent design aids. 4. Intelligent design methodology Intelligent design methodology is the main features: design methodology based on the 6 theory that through 3D graphics software, intelligent design software and virtual reality technology, and multimedia, hypermedia tools for product development design, the idea expressed products, product description of the structure. In the use of mathematical systems theory, taking into a systems engineering theory, product design and system development methodologies VDI2221 technology, developed for use in the initial design of multimedia products developed software Muse.
