Assessment and Optimization of Pedestrian Head Impact Safety Performance for a SUV Car

Based on evaluation procedures of pedestrian protection (Euro-New car Assessment Program, Euro-NCAP), using CAE (Computer-Aided Engineering) and physical test, the pedestrian head impact safety performance was evaluated. Detailed analysis was done for Key factor which affect the performance of pedestrian head impact. The structure design optimization was performed of the front-end, including Hood, Fender and Cowl top for a SUV car. The final assessment results show that the optimized front-end structure meet the requirements of Euro-NCAP pedestrian protocol, in favor of the pedestrian protection performance improvement. Thereby, the paper provides best reference for the front-end structure design on SUV Cars.
