| 摘 要： | 介绍了路面国际平整度指标计算原理，设计了基于高精度激光测距传感器和加速度传感器的路面平整度检测系统，采用截至频率为20Hz的二阶巴特沃斯低通滤波器和零均值化对检测车垂直振动加速度数据进行预处理，同时利用直接积分法计算检测车垂直振动位移。实验结果表明，检测车垂直振动位移计算结果与实际测量值基本吻合。

| Abstract: | When vehicle sensors are used to inspect international pavement roughness index,it is needed to calculate the displacement of vehicle vibration,and to modify data of the pavement elevation.This paper introduces the inspecting principle of international roughness index,and uses the precision laser and acceleration sensors to design inspecting system of pavement roughness.The study designs a second-order Butterworth low-pass filter whose stopband is 20 Hz and it makes a mean normalization processing on-vehicl... |
