A Study on Kinematic Behavior and Head Injury Rick in Vehicle to Pedestrian Collisions

Pedestrian kinematic behavior during vehicle impact could influence the pedestrians´ bodies injuries. The THUMS pedestrian and four vehicle FE models with different front-ends (medium car, minicar, one-box vehicle and SUVs) was used to verify the kinematic of the body´s segments. The head impact conditions, head injury response and injury risk were investigated at diffent velocity of 20, 30 40 and 50 km/h. The results demonstrate that the vehicle front shape and vehicle impact velocity are two important factors influence of the pedestrian kinematics and injuries. The design tendency of short front-end and wide windscreen area can be achieved the protection of the pedestrian from fatalities.
