钢索公路护栏的拦截性能研究

Experimental Study on Safety Capability of the Wire Rope Fence

在汽车与公路护栏碰撞事故中,护栏不仅有拦截、导向作用,还要有良好的缓冲吸能特性,以减小由于乘坐空间过度变形以及人与车内物体二次碰撞对乘员的伤害。通过实车与钢索护栏的碰撞试验,研究了护栏、汽车和乘员的动态响应特性,结果表明,钢索护栏完全符合要求,可为高速公路护栏的设计、施工以及在不同地点的设置提供借鉴。

In the impact accident between vehicle and fence,the fence not only has the functions to resist and guide the vehicle,but also has the character of absorption to diminish the injury on occupants for deforming overly of cab or playback impact.In this paper,impact experiments are executed in conditions of the Wire Rope Fence,the dynamic characteristic and the relations among fence,vehicle and Occupants are analyzed.The result is benefit for the design of vehicle and fence.
