【正文】 ponents design, process planning, operational control of the foundation, from the macroproduct development process starting, the use of qualitative methods of functional layout, systematic information to users needs rational and effective products into all stages of development objectives and technical control of the operations. (2) See product as the level of product life systems of anisms, and by systems theory to life the product design process can be divided effectively as demand levels, the achievement of the functional requirements of the specific design and product concept level. At the same time the use of life chart at abstract expression products functional requirements, and form the architecture of the products system. (3) Mechanical design system science applications into two basic issues: First, the design of products as a system to deal with, the best set of its ponents (modules) and their interrelationship。 4) A modular structure and modular ponents connectivity. And the use of symbols that prospective typical ponents and the interlinking ponents rules, thus achieving connectivity between the ponents of the algorithms and concepts visualization. 3. The characteristics of knowledgebased products in the design methodology Design methods based on product characteristics knowledge of the main features: 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 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 e
