RAIL WAVY WEAR DETECTION DEVICE, AND RAIL WAVY WEAR DETECTION METHOD
To provide a rail wavy wear detection device of which detection accuracy is improved.SOLUTION: This rail wavy wear detection device comprises: an acceleration sensor 11 which is a measuring apparatus which measures at least one of a vibrational acceleration and a noise to a travel time of a railway vehicle 10 which travels on a rail 25, and acquires time base data D1; and a CPU 13a which is an arithmetic unit which performs high-pass filter processing, performs absolute value processing, and performs low-pass filter processing of the time base data D1 thereby making high frequency vibration data D2, and convers the high frequency vibration data D2 into space axis data D3.SELECTED DRAWING: Figure 3
【課題】検出精度を高めたレール波状摩耗検出装置の提供。【解決手段】レール２５上を走行する鉄道車両１０の走行時間に対して振動加速度または騒音の少なくとも一方を測定して時間軸データＤ１を取得する測定装置である加速度センサ１１と、時間軸データＤ１をハイパスフィルタ処理し、絶対値処理し、ローパスフィルタ処理して高周波振動データＤ２とし、高周波振動データＤ２を空間軸データＤ３に変換する演算装置であるＣＰＵ１３ａと、を備える。【選択図】図３
