METHOD FOR DETERMINING WHETHER TRACK MAINTENANCE IS REQUIRED, DEVICE FOR DETERMINING WHETHER MAINTENANCE IS REQUIRED, AND VEHICLE
To provide a technology to rationally determine whether or not track maintenance is required, based on the feeling of the ride and taking into account variations in track irregularities.SOLUTION: A determination of whether a track requires maintenance is performed by the following steps of: dividing the waveform data of a measurement section into waveform data of small sections; calculating the spectrum of the waveform data of each small section broken down into frequency components; calculating the distribution of frequency components for each frequency; calculating the probability that the spectrum consisting of the distribution of frequency components exceeds the control value of the spectrum; and determining that the track requires maintenance if the probability of exceeding the control value exceeds the control value of the probability.SELECTED DRAWING: Figure 1
【課題】乗り心地の感じ具合に基づき、軌道不整のばらつきを考慮した上で、合理的に軌道の保守要否を判断する技術を提供する。【解決手段】軌道の保守要否判断を、計測区間の波形データを小区間の波形データに分割するステップと、各小区間の波形データを周波数成分に分解したスペクトルを算出するステップと、周波数毎に周波数成分の分布を算出するステップと、周波数成分の分布からなるスペクトルがスペクトルの管理値を超える確率を算出するステップと、管理値を超える確率が確率の管理値を超える場合、軌道の保守が必要であると判断するステップと、によって行う。【選択図】図１
