| Abstract: | In order to realize the engine hood lightweight, the authors use the aluminum alloy materials to make the engine hood. Based on the stiffness and the pedestrian protection, they apply the OptiStruct optimization software to design a new type of inner aluminum alloy plate structure. Comparing the original steel hood, it reduces weight 46.4%, and the pedestrian head protection, stiffness and modal performance are not lower. |
