碰撞试验中乘员颈部运动及其受力分析

汽车碰撞交通事故发生时，人体各个部位都会受到不同程度的伤害。人们通过事故统计、生物力学分析等途径试图更加深入了解事故发生时人体受伤害的过程，以便对车辆的安全性能做出相应的改进，降低事故发生时人体受到损伤的程度。颈部的伤害是车辆发生碰撞时人体较易发生的伤害之一，通过对碰撞发生时颈部运动分析，从实际人体结构及试验用假人结构等方面着手，结合实车碰撞试验的具体数据，力求更加清晰地了解颈部伤害的过程，为进一步的试验分析提供有益的理论基础。

Research on Neck Motion and Neck Load in the Impact Test

In the traffic accidents, there are many kinds of injuries on the human body. People try to understand the injury process, and improve the vehicle safety, at the same time reduce the injury degree. Neck injury is prevalent in the traffic accidents, the neck motion was analyzed in the impact test, and the structure of the ATD was discussed based on test data, which provide theoretical foundation for further test analysis.
