【摘要】 轿车追尾轿车道路交通事故,前车乘员颈部损伤相对严重,主要特点是"挥鞭效应"。采用三维有限元动态仿真技术研究汽车追尾碰撞过程,经过试验验证对应特征参数相近或者相似的情况下,能够分析前车假人颈部损伤情况,并进行安全性评价。仿真研究的结果表明,前车假人颈部的最大前屈和后屈转矩都在评价标准的安全范围之内,但已经接近临界值。这项研究对汽车的安全性设计、安全设施的配置和交通安全的管理有一定的指导作用。更多还原

【Abstract】 The front car occupant’s neck will have worse scathe at car rear back collision traffic accident. The main characteristic is "Whiplash Effect". Study on car rear back collision course by three-dimensional Finite Element dynamic simulation and test validate. It can be analyze the front car occupant’s neck scathe and safety evaluate. The simulation results indicate the maximal moment of proneness and retroversion all within safety scale of evaluate criterion, but it is close to critical. This research will some effect for car safety design, safety establishment collocate and traffic safety manage, and so on.更多还原
