Abstract:

The simulation tests were conducted with the Pc-Crash software based on the measured data of 411 vehicles’ head shape to obtain more information about the influence of the vehicle head shape on the dynamic response of the pedestrian in vehicle-pedestrian accidents. All parameters about the dynamic response of the pedestrian were measured. A exist parameter sensitivity analysis method was adopted to analyze the sensitive of the vehicle head shape. The results show that in the orders of 8 sensitivity parameters used to describe the pedestrian dynamic response, the first is the height between the front windshield bottom and the ground, the second is the length of hood, the last is the height between the bumper bottom and the ground. Combining the velocity analysis, the orders of the sensitivity parameters is velocity, the length of car head, the height of car head. It is clarified that the most sensitivity parameters is the height between the front windshield bottom and the ground among the 8 parameters which have the influences on difference dynamic response. The research is practical meaningful in the fields of accident area, the trace measurement and the design of the vehicle shape.
