摘　　要：针对我国城市道路频发的车辆碰撞道路隔离栅的交通事故问题,基于青岛市道路隔离栅建设情状及交通现状,设计出一种适应于城市道路的新型柔性道路隔离栅.选取其中1种应用最为广泛的隔离栅设计,在分析学习碰撞理论的基础上,利用有限元仿真软件建立车辆-隔离栅碰撞模型,仿真分析新型柔性隔离栅的安全性、适用性.Aiming at the problems of the frequent fence traffic accidents caused by the city road vehicle collision and basing on the situation of Qingdao city road construction and traffic isolation,this paper designs a new type of flexible isolation grid which is suitable for urban road.On selecting one of the most widely isolated gate designs and basing the analysis of study on collision theory,it uses a finite element simulation software to establish vehicle barrier collision model,and analyzes the safety and applicability of new flexible isolation grid.
