An intelligent system for vehicle structure concept design

This paper describes a research project to implement vehicle body structure design in early stages of a new vehicle program. In order to dramatically reduce the design mistake of traditional method for vehicle structure concept design, an intelligent system has been implemented based on UGS NX/API opening platform, which is named CVD (Concept Vehicle body Design) System. In this system., a template method is adopted to build body concept geometry model and FEM model quickly and easily. It also integrates body modeling, analysis and optimization on one CAD platform by the parametric variables database and all of parametric variables would be shared or updated on different phase of CVD System. A wizard User Interface based on knowledge is used in the system, which makes user's manipulation become more easer. The procedures of the implemented and the CVD system function diagram are provided in the present paper. An example proves that CVD system has good efficiency and right answer.
