摘　　要：依据1/4车模型,分析了基于惯性基准的路面平整度检测方法,给出了采用激光测距仪和加速度传感器的输出信号获得待测路面纵断面相对高程的计算公式,实现了多路数据的同步采集与联合处理,介绍了对传感器输出信号的数据处理方法。通过与精密水准仪测量方法进行对比试验,结果表明基于惯性基准的检测方法在路面平整度检测中是可行的。According to 1 quarter car model, a pavement roughness testing method was analyzed based on inertia benchmark. The formula of profile level computation were given by using height sensor data and accelerometer signals. Thus, the combination of the two signals was realized. The data processing method of sensor signals was expounded. The actual road tests prove that this method, which is based on inertia benchmark in pavement roughness testing, is available.
