According to the dimensional constrains of automotive body styling, interior space and packing in conceptual design phase, taking into account the shape constrains of the formability of pressed metal sheets, proposes a cross-sectional shape optimization generating method for achieving the cross-sectional properties assigned was proposed by design engineers. Using grid ideas, the method dispersed the feasible design domain of a cross-section into a number of discrete nodes, which controled the shape of the section. Based on ant colony optimization algorithm, the relevant mathematical models and corresponding programs were established. A application has proved this method is suitable for automotive engineering.
