The invention discloses a straddle type monorail track surface smoothness detection method. The method comprises the following steps of step 1, installing a fiber-optic gyroscope on a track inspectiontrolley, and collecting an inclination angle value of the track inspection trolley by using the fiber-optic gyroscope; mounting a rotary encoder at a wheel of the track inspection trolley, and measuring the travelling mileage of the trolley; taking the measured inclination angle and mileage as a to-be-calculated data sample; 2, performing digital signal processing on the to-be-calculated data sample to obtain an effective data sample; and 3, calculating the effective data sample by adopting an inertia track method and a curve interpolation fitting method to obtain track surface smoothness evaluation. The method is advantaged in that longitudinal and transverse surface smoothness of the track can be effectively detected by utilizing an inertia track method and a curve interpolation fittingmethod, and the method has the characteristics of good measurement precision, high efficiency, excellent repeatability and the like.

    本发明公开了一种跨坐式单轨轨道表面平顺性检测方法,包含以下步骤:步骤1、在轨检小车上安装光纤陀螺,用光纤陀螺采集轨检小车的倾角值;在轨检小车车轮处安装旋转编码器,测量小车的行走里程;将测量所得的倾角、里程作为待计算的数据样本;步骤2、将上述待计算数据样本进行数字信号处理,获取有效数据样本;步骤3、采用惯性轨迹法和曲线插值拟合法对有效数据样本进行计算,得到轨道表面平顺性评价。本发明利用惯性轨迹法和曲线插值拟合法能够有效检测轨道纵向和横向的表面平顺性,具有测量精度好,效率高,重复性优秀等特点。
