Abstract
All car manufacturers are recently required to develop the engine-hood for the purpose of protecting pedestrian heads. The engine-hood is evaluated by the pedestrian head protection performance test according to the HIC. It is important to control the acceleration time history at the initial stage and late stage for pedestrian head protection. This study also aimed to evaluate that impact characteristics of inner panels adopting corrugated panels improve pedestrian head protection by numerical analysis. As a result, the corrugated panel structure helped control the amount of displacement and it was effective in reduction of HIC.
