Traditional optimization design ignores the effect of noise and design variables, which would make the objective function out of range, and excessive reliance on safety factor can also cause redundancy optimal design. Therefore, it is particularly important to set up design parameters properly in frame structure design stage, which can ensure the robustness of structure. With the development of computer technology and finite element theory, computer aided engineering technology is widely used in industries such as aerospace, automotive, and a large number of results have been achieved. The method which using advanced finite element software to analysis vehicle
