Interrelation between Wavelengths of Track Geometry Irregularities and Rail Vehicle Dynamic Properties

Journal Title: Archives of Transport - Year 2013, Vol 25, Issue 1

Abstract

The paper deals with the problem of railway track irregularities appearance in form of so-called short waves (3-25m). These geometrical irregularities were found in measurements, which were carried out on different railway tracks of Polish Railway Lines. Those tracks can be classified as tracks with good state of maintenance. The article describes the results of the analysis of geometrical irregularities of these railway tracks in frequency domain and demonstrates their statistical characteristics. The studies, in contrast to usually used approach to the analysis of the geometry of the track, are focused on the left and right rail alignment and their longitudinal level. Based on studies of different mathematical models of railway vehicles it was found the relationship between their eigenvalues and wavelengths of track geometrical irregularities. Analysis of the measurements results of car-body acceleration and bogie frame acceleration confirms the thesis that the deterioration of railway track is dependent on the dynamic influences of vehicles on the tracks.
