摘 要：It is very important to obtain an ideal basic shape with optimal aerody namic characteristics in the auto-body styling design based on the whole shape optimization.Through obtaining the solutions for conflict problem in the auto-body styling aerodynamic design cooperating extension engineering, a variable cross-section method based on aero dynamic theoretical model to obtain ideal basic shape for car body is proposed.A theory model based on aerodynamics is developed.In addition, a generation method for a series of ideal basic bodies with favorable aerodynamic characteristics is developed, which enables the generation of these basic bodies by a variable cross-section method.This method is finally realized and it is shown in the evaluation that it is a new way for the auto-body styling design based on whole shape optimization.
