Abstract

In vehicle-pedestrian impacts, the severity of pedestrian injuries are affected by car hood. The structure and material of the hood is believed that strongly effect on pedestrian head injury. Therefore, the improvement design of hood structures has a great help for reducing pedestrian head injuries. In order to reduce injuries of pedestrians in case of accident, the aluminum foam as a hood material is proposed in this study. This study constructs the finite element model of headform impactors and pedestrian friendliness of a vehicle hood using LS-DYNA software based on the EEVC WG17 regulation. Aluminum foam is applied on the hood structure for minimizing pedestrian head injury. To confirm the feasibility of aluminum foam as a hood material, the resultant acceleration of head center of gravity and HIC value are measured, and the results of new hood material are compared with the original material.
