ABSTRACT The present article is a continuation of [21] and [22]; after the examination of the reliability of the recordings of the defects on Track by the Track Recording Cars, it presents real graphs of recordings of some Track parameters, the Spectral Densities for the defects of leveling and examines the Dynamic Vertical Stresses on the Trackbed due to the Excitation Spectra of the Track, the Response of the “Track-Vehicle system” to the Track defects in relation to their Spectral Density, a Statistical Analysis of Spectra of the Track Recordings, as well as the utilization of Spectra to make correct decisions for the Track maintenance works. The real data being presented in the article resulted from theoretical and experimental investigations to which the author participated since the cooperation between experts of Greek and French State Railways (1988-1989) until quite recently (2025). |
