摘  要:
通过分析道路交通事故中汽车与行人碰撞的特点,建立常见人车碰撞事故的汽车运动学模型和碰撞模型,利用计算机进行数值模拟仿真,计算出相应的动力学参数及碰撞后行人的运动状态,分析行人头部与车体前部碰撞点以及损伤程度的分布规律,最后,在改善发动机罩结构和性能以及安装前风窗安全气囊或采用辅助制动装置等方面提出有效的保护行人的措施。

摘  要:
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 impact 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 auxiliary braking devices,etc.
