Summary:

Hood development of internal structures in vehicles is animportant alternative to minimize the injuries to pedestrians incase of a running over accident. In fact, according to Berg et al(2002), about 17% of head impacts occur on the hood. Moreover,according to Farooq and Schuster (2003), 62% of fatal injuries arecaused by head trauma.This study focuses on evaluating the influence of free spacebetween the hood and rigid components, considering cut out hoodinner panel design, which is one of the geometries most commonlyused by auto industries. The major advantage of this structure isits weight, leading, however, to small stiffness.Injuries to the head of a pedestrian is measured through afinite element model, in accordance with the European Committee forimprovement in vehicle safety. There are several ways to measurethe damage caused by the deceleration of the head. Here, themeasure HIC (Head Injury Criteria), created by the NHTSA (NationalHighway Transport Safety Association) in 1971, is chosen, since itis still the most used and recommended method in theliterature.Finally, the analyses of the numerical results lead to practicalsuggestions for auto industry
