A new methodology for optimal rail track condition measurement using acceleration signals

Abstract: This paper describes the possibility of estimating the health of a rail track in order to improve the comfort and ride quality of rail transportation by using the measured acceleration signal. The irregularities present in the track are the primary causes of vibration and these should be identified and the faults rectified to increase the safety of train travel. In this paper, a differential evolution technique based track measurement system (DE-TMS) is proposed to measure the health of the track. The abnormal… Show more

“…The algorithm is closely related to principal component analysis and extracts the principal dynamics from measurement data. A differential evolution technique based track measurement is presented in the paper [35], where the axle box measurements are considered. The new method enables to estimate the exact location of the irregularity.…”
