Abstract
This paper aimed at investigating countermeasures for the head protection of the pedestrians involved in car front impacts. A validated human-body mathematical model was used as a pedestrian substitute in computer simulations of car-pedestrian impacts. The pedestrian head responses to the bonnet top impacts were studied in terms of head injury related parameters that were used to evaluate the risk of pedestrian injuries in vehicle impacts. The influence of the bonnet to responses of the pedestrian head was analyzed with varying car-front parameters. Furthermore, the possible protective system was presented. (Author/publisher).
