路肩隆声带是警示驾驶人提高注意力,减少单方事故的一种有效的道路安全设施。为了评价路肩隆声带对车辆的安全性影响,提出了采用车辆前轴振动加速度值、方向盘振动角加速度值作为车辆冲击状况和方向稳定性的评价参数。在3种车型、5种型式隆声带道路试验的基础上,建立了定量描述路肩隆声带主要结构尺寸与安全性能评价参数之间的经验模型,为路肩隆声带的应用安全效果分析提供了工程计算方法。
The shoulder vocal cord is an effective road safety device that warns motorists to increase their attentiveness and reduce unilateral accidents. In order to evaluate the influence of the road noise barrier on the vehicle safety, the acceleration acceleration value of the front axle and the acceleration value of the steering wheel vibration angle are proposed as the evaluation parameters of the vehicle impact status and direction stability. Based on the road tests of 3 types of models and 5 types of rumble strips, an empirical model was established to quantitatively describe the main structural dimensions and safety performance evaluation parameters of the rover rumble, which provided an engineering calculation for the application of the safety effect analysis of the rumble strips method.
