Virtual design can minimize production costs and shorten the development cycle , improve the core competitiveness of enterprises is the era of knowledge economy , is the technical foundation for enterprise innovative design . Knowledge base as a key technology in the virtual design is an intelligent database , a collection of various data for use in the production process , rules and field experience . Therefore, based on the knowledge base of the development and application of virtual design system has important theoretical and practical significance . Based on fuzzy sets , rough sets mathematical theory to build cars alloy wheels virtual design knowledge base the discrete car alloy wheels design process knowledge , including design data , design rules and design experience , reorganization , in an appropriate form easy instance and rule-based reasoning . On this basis, the use of UG secondary development tools GRIP developed set embedded in the UG platform \modeling of each module , thus completing the three-dimensional shape of the entire passenger car aluminum wheel products . Finally, the cars alloy wheels experimental methods , simulation using ANSYS software designed car alloy wheels bending fatigue , radial fatigue and impact tests , and improve the system . Cars alloy wheels virtual design system based on knowledge base can significantly shorten the cars alloy wheels design cycle and improve design efficiency. Aluminum wheel products and the design of the cars high degree of parameterization , feature simple , in line with the requirements of the design standards of the industry . This paper sedan alloy wheels virtual design system similar to the rapid design of non-standard parts , provide ideas and methods .
