Car - Pedestrian accidents cause a loss of thousands of lives annually in addition to injuries. Therefore, pedestrian protection is one of the important issue in the design of friendly cars. This study shows the performance of finite element head model (FEM) to study and foretelling the extent of injury that occurs at pedestrian accidents and tests the design of the front of vehicle according to European Enhanced Vehicle-Safety Committee (EEVC WG17) regulations of bonnet test. The FE models are powerful tools and effective method to understand how to reduce the sever ity of the fatalities of injuries in road pedestrian collision incidents. In this study, the finite element head model impactor has been built by using Soldworks program and simulated the impact process in LS-DYNA program to examine the four engine-hoods have been designed. All of the hood plates and inner hood panel were considered. Head Injury Criterion (HIC), internal energy time history generated in the head and hood, displacement occurred in the hood i nner panel and weights of the complete hood are investigated. The results of the study concluded that modification of headform des ign of the car hood contributes in achieving low HIC and lead to a pedestrian friendly car. The results show that the structural design of the inner hood panel is one of the key factors affecting the design and specifications of car hood. Introductionresearch studies of pedestrian protection were dependent on true incidents occurred, these recorded accidents used as a base statistical data, there was a lack of reference information about how to reduce the effect of car collision with pedestrians. The high collision number of pedestrian with vehicles has drawn considerable attention to many researchers in USA. Since 1977, the debates and studies were concentrated on how to protect pedestrians and reduce the effect of collision impact by vehicles because of the growing number of deaths and severed injuries
