| Abstract(E) | In this paper, the MDO analysis is applied to the design integration in terms of NVH and crash safety. Considering the difference of characteristics in these two fields, all the design variables are used to construct the response surfaces in the NVH analysis, while for crash safety analysis, these design variables are split into three groups, front, side and rear, to reduce the computational cost. Many of the structure performance indices in the NVH and crash safety fields are included as the constraints in the MDO analysis, which proves that the design integration of these two fields through MDO analysis is feasible. A comparison of crash safety optimization and crash safety-NVH MDO is done through a parallel-coordinate diagram. The difference provides the CAE engineers to find the guidance to modify the original design architecture. |
