PROGRESS DETECTION METHOD AND PROGRESS DETECTION SYSTEM OF RAIL WAVY ABRASION
To provide a progress detection method and progress detection system of a rail wavy abrasion which can properly detect a rail wavy abrasion that reaches a saturation period or gets close to the saturation period in progress processes in three stages of irregularities of the rail wavy abrasion.SOLUTION: A progress detection system of a rail wavy abrasion comprises: measurement means which measures data of at least one or more of the vibration acceleration, deviation and pressure distortion generated on a railroad due to the external force from a railway vehicle traveling on a rail, or the noise around the railroad on the rail or in the vicinity of the rail; frequency analysis means which frequency-analyzes the measurement data of at least one or more of the vibration acceleration, deviation and distortion or the noise around the railroad measured by the measurement means; detection means which detects the fundamental frequency and the harmonic content of the fundamental frequency from the data that is frequency-analyzed by the frequency analysis means; and output means which outputs the information that the rail wavy abrasion progresses when the harmonic content is detected.SELECTED DRAWING: Figure 1
【課題】レール波状摩耗の凹凸の三段階の進展過程のうち、飽和期に達した、あるいは飽和期に近づいたレール波状摩耗を適切に検知することができるレール波状摩耗の進展検知方法および進展検知システムを提供する。【解決手段】レール上を走行する鉄道車両からの外力によって軌道に生じた振動加速度、変位、圧力ひずみあるいは軌道周辺の騒音の少なくともいずれか一つ以上のデータを前記レールまたは前記レールの近傍で測定する測定手段と、前記測定手段によって測定された振動加速度、変位、圧力、ひずみあるいは軌道周辺の騒音の少なくともいずれか一つ以上の測定データを周波数分析する周波数分析手段と、前記周波数分析手段によって周波数分析されたデータから基本周波数及び該基本周波数の高調波成分の検知を行う検知手段と、前記高調波成分が検知された場合にレール波状摩耗が進展していることを出力する出力手段を備える。【選択図】図１
