Images of Vibrations of a Passing Railway Vehicle

Abstract

The paper presents the results of preliminary rail vibration tests generated by the passage of a rail vehicle. As part of the study, vibrations were recorded in three orthogonal axes, analyzing longitudinal, transversal and vertical vibrations. The results show time waveforms, signal spectra and time-frequency distributions. On the basis of the analysis of each of the forms of signal presentation, various vibration properties and interrelationships between propagation axes can be observed.
