Motor vehicles on the market have been required to undergo the pedestrian head protection test since 2004 and engine-hoods need to meet the required standards for pedestrian head protection performance in addition to primary performance. The quality of engine-hood is evaluated by Head injury criteria (HIC) derived from 3-dimensional acceleration generated against the head. Based on HIC measurements, the authors tried to improve it is performance by using the hood with two panel structure. In this study, we examined impact response characteristics of the pedestrian head by numerical analysis. We focus on the brain concussion and the skull fracture as a severe injury to be injured at the time of an engine-hood collision. As a result, we revealed about mechanism of the head injury occur by dynamic deformation behavior of the engine-hood.
