| 摘 要： | 提出了一种新型柔性吸能防撞产品——FCZ轮辐式桥墩防撞安全装置,采用大型通用有限元软件Ls-Dyna,对设置FCZ装置后的桥墩,进行了汽车碰撞仿真建模和数值分析,并分别从构件级别和"车-桥墩碰撞系统",对防撞装置和桥墩进行了保护能力评价。由于桥墩受到车辆高速撞击的安全隐患巨大,专门就桥墩未设置保护措施进行了碰撞计算,与设置FCZ装置后的碰撞结果做了对比分析,验证了该装置的良好技术性能。

| Abstract: | The performance evaluation and numerical analysis of the flexbile energy-absorbtion anti-crash instrument FCZ are performed in this paper.The FEM model of FCZ is implemented by commercial finite element software Ls-dyna for the vehicle impact.The protection efficiencies in FCZ’ components details and vehicle-column collision system are addressed specifically.To clarify the potential catastrophe caused by the high velocity vehicle-impact of the columns without any protection,a comparison between the column with FCZ and without FCZ protection is made in this paper. |
