摘　　要：为了实现基于多目标驾驶员保护的桥墩防护结构优化设计,以解决车辆意外撞击桥墩导致驾驶员受伤的问题。文章提出一种泡沫蜂窝铝吸能防护结构,通过整车约束系统仿真分析方法,采用Hybrid Ⅲ 50th假人驾驶员,在车辆与桥墩正碰、内偏30°、时速45km/h的工况下,分析泡沫蜂窝铝厚度对驾驶员头部、胸部、大腿以及综合损伤的影响。研究表明:降低事故中驾驶员头部和胸部的伤害是桥墩泡沫蜂窝铝吸能防护结构设计的重点,增加泡沫蜂窝铝的厚度能够有效减少假人损伤超限项。泡沫蜂窝铝桥墩防护结构在车辆意外撞击桥墩事故中对驾驶员的保护作用明显。In order to realize the optimal design of pier protection structure based on multi-objective driver protection,the problem of driver injury caused by vehicle accidental impact on pier could be solved.In this paper,a foam-cellular aluminum energy absorption protection structure is proposed.Through the simulation analysis method of vehicle restraint system with a Hybrid III 50th dummy driver,the effects of foam-cellular aluminum thickness on the driver’s head,neck,chest,thighs,calves and overall damage under the scenarios of frontal collision,30°inward deviation and 45km/h speed.The research shows that reducing the injury of the driver’s head,neck,chest and calves in the accident is the focus in the design of bridge pier foam-cellular aluminum energy absorption protection structure,and increasing the thickness of foam-cellular aluminum can effectively reduce the excessive injury of the dummy.The foam-cellular aluminum bridge pier protective structure demonstrates significant protective effects for drivers in the unintended accidents of vehicle collision with bridge pier.
