摘　　要：为了降低错误行驶车辆对养护施工作业区造成的人员伤亡,提出了一种安装在道路养护车辆尾部的铝蜂窝式防撞缓冲垫。目前针对该类型防撞缓冲垫的研究较少,为此搭建了高精度防撞缓冲垫碰撞有限元模型,并利用数值仿真的方法,从吸能性能、可导向性能和阻挡性能三方面对铝蜂窝式防撞缓冲垫的防撞性能展开研究。研究结果表明,铝蜂窝式防撞缓冲垫可有效降低碰撞过程中司乘人员受到的冲击力和加速度。另外,合理的铝蜂窝强度对提高防撞性能至关重要。In order to reduce casualties caused by improperly driven vehicles in maintenance construction zones,this paper proposes an aluminum honeycomb attenuator installed at the rear of road maintenance vehicles.Currently,there is limited research on this type of attenuator.To address this,the paper establishes a high⁃precision finite element model for the attenuator and utilizes numerical simulation methods to study its collision protection performance from three aspects:energy absorption,directional controllability,and blocking capability.The research results indicate that the aluminum honeycomb attenuator can effectively reduce the impact force and acceleration experienced by occupants during collisions.Additionally,the appropriate strength of the aluminum honeycomb is crucial for enhancing collision protection performance.
