TRACK IRREGULARITY MEASURING DEVICE
To provide a track irregularity measuring device which has a simple structure and an improved measurement accuracy.SOLUTION: This disclosure relates with a device measuring an irregularity of a track with two rails. The track irregularity measuring device comprises a measuring part traveling along at least a rail of the two rails, an inertia measurement device which is arranged in the measuring part and measures an angular velocity and an acceleration and a processor processing an output of the inertia measurement device. The processor, while calibrating an inclination of the inertia measurement device that is not caused by a condition of at least a rail, by the use of the inertia measurement device output, calculates the condition of at least a rail.SELECTED DRAWING: Figure 1
【課題】構造を簡略化しつつ、測定精度を高められる軌道狂い測定装置を提供する。【解決手段】本開示は、２つのレールを有する軌道の狂い測定装置である。軌道狂い測定装置は、２つのレールのうち、少なくとも１つのレールに沿って走行する測定部と、測定部に配置された角速度及び加速度を測定する慣性計測装置と、慣性計測装置の出力を処理する処理装置と、を備える。処理装置は、慣性計測装置の出力を用いて、少なくとも１つのレールの状態に起因しない慣性計測装置の傾きを補正しつつ、少なくとも１つのレールの状態を算出する。【選択図】図１
