Abstract
Conical aluminum engine inner hood was designed based on Euro-NCAP pedestrian protection analysis by structure optimization design methods. The Constitutive relationship of aluminum alloy based on dynamic tensile tests was adopted to achieve the crash simulation. The stiffness performance and pedestrian protection performance of the optimal structure was validated by CAE Simulation. The results indicate that the optimized hood structure shows similar stiffness performance when it compared to original steel structure and better pedestrian protection performance than the original ones. In addition, the optimized hood structure realizes weight reduction of 46.4% compared with the original steel one.
