| 摘 要： | 为了更加准确地测出不同状态下路面摩擦系数,采用三轴加速度仪测量车辆制动过程中的加速度变化过程.经过低通滤波后,分析出了车辆在制动过程中的加速度变化规律,并根据现场试验的结果给出了旧沥青混凝土路面、水泥混凝土路面、积雪覆盖的路面、新建高速公路沥青混凝土路面和水泥混凝土路面的摩擦系数值.试验结果为交通安全分析提供了最直接的依据.

| Abstract: | In order to measure pavement friction coefficient under different conditions,three-axes acceleration apparatus is employed to measure vehicle acceleration during emergency braking.After low pass filtering,acceleration changing is analyzed,and friction coefficient of old asphalt and concrete pavement,snow-covered pavement,newly built asphalt concrete and cement concrete pavements are supplied.The results have great significance on traffic safety analysis. |
