| Abstract: | The characters of the vehicle-pedestrian collision traffic accidents were analyzed through statistical analysis, hereby, the vehicle kinetic model and the vehicle-pedestrian collision model were established. The kinetic specifications and the pedestrian＇s postures after impaction were calculated based on computer numerical simulation, and the location distribution of pedestrian＇s head im- pact on vehicle front body and the injury grades were analyzed. In conclusion, the effective pedestrian protection steps were brought up, such as innovative improvement of the basic structure of hood, fixing front windshield airbags, or auxiliarv brakinz devices, etc. |
