滑动式交通防撞护栏的特点与作用机理

Characteristics and Mechanism of Sliding Traffic Guardrail

滑动式交通防撞护栏改变了传统护栏在汽车与之相撞时的受力方式,可以使汽车与护栏间的摩擦力趋近于零,使偏离正常车道与护栏相撞的车辆方向得到修正,以免汽车冲出护栏,迫使车辆驶回到正常的行驶车道上,特别适合高危路段的路侧防护。

Sliding traffic guardrail changes the force mode of traditional barrier when it collides with vehicle. It can make the friction between the vehicle and guardrail approach zero, and correct the direction of vehicle which collides with guardrail and deviates from normal driveway, in order to prevent the vehicle from dashing out the guardrail and force the vehicle to drive back to normal driveway. It is very suitable for the roadside safety on high risk highway.
