Development of Shape Optimization Technique Based on The Basis Vector Method

A practical shape optimization technique is presented. We employed the basis vector method to parameterize the shape of the structural domain that is usually discretized by the finite element method. VMA/GENESIS software, the optimization system with finite element analysis, sensitivity analysis, and numerical optimization capabilities, was used for this study. Various design problems such as body, chassis, and engine parts design are solved to demonstrate the effectiveness and the robustness of the present approach for automotive applications.
