차량 구조강성 및 보행자 머리 상해를 고려한 Hood 형상 최적화

다국어 초록 (Multilingual Abstract)

Recently pedestrian’s safety has been a major problem in the automobile industry. It became important as well as driver’s safety. Crashing with car causes the dangerous factors, especially to child because of these factors, some countries like Europe, USA and Japan has already established their own rule of safety for pedestrian and implemented it. In this study, we change the shape of hood inner panel to reduce HIC of child pedestrian. We applied EuroNCAP on our study. We determined only the middle range of hood among WAD’s 1000 to 1250 because our model is the compact car. This study’s object is reduction of HIC. So we figured out the number of optimal ribs, and applied design of experiment (DOE) to find optimal rib shapes. Then we applied hole and change of the hood side shape to reduce HIC of child head injury. In addition, only for considering the design of pedestrians safety might cause structural problem as for this problem we have simulated the structure of hood for all kinds of possibilities.
