摘　　要：轨道平顺性是高速铁路安全的重要保障参数,在分析弦测法、光学测量法、惯性基准法及光学摄像法4种常用轨道平顺性检测方法的基础上,研究了惯性连续检测方法。该方法采用中等精度光纤陀螺作为主要传感器,对左、右高低和轨向进行分别测量,设计了专用分组地推算法,能够适应各种速度下的高精度连续检测。最后,对该方法的核心部分进行了实验仿真。结果表明,惯性连续检测方法的惯性器件平顺性检测精度小于0.3 mm,总误差小于1 mm,满足平顺性检测指标要求,为研制新一代轨道检测设备奠定了基础。To ensure the security of high speed train and the comfortableness of passengers,the track vertical and alignment smoothness should be tested accurately.Firstly,the measurement principles of the track irregularity inspecting system in-out country are analyzed.Secondly,inertial uninterrupted measuring method is studied deeply.This new method tests the left and the right track vertical irregularity and the track alignment irregularity respectively.The new system composed by three closed-loop fiber optic gyroscopes,four laser displacement measurement sensors,one odometer and computers can test the track irregularity continuously and effectively in all kinds speed.At last,experiment results show that the inertial sensor error is low than 0.3 mm and the total error is better than 1 mm.The new method is surely a good preparation for practical application.
