METHOD OF EVALUATION OF CONDITION OF RAIL TRACK WITH FLOTTING OF TRIVARIATE SPECTRAL CHART

摘要

FIELD: railway transport; checking and evaluating condition of rail tracks. SUBSTANCE: measuring device is moved along rail track and outline of rails is recorded. Sliding spectral analysis of recorded outlines is carried out. Intensity of harmonic components as a function of sliding coordinate of track and wavelength is determined. Basing of obtained results, speeds of cars at different loads and coordinates of tracks in which resonance can appear are determined. Outlines of both rail lines are recorded, and sliding analysis is carried out by harmonically conjugated functions of track by obtaining spectrum of complex coordinate of pairs of rails and/or pairs of parameters of outlines of one rail line. EFFECT: provision of resonance safety of rail vehicle running owing to early diagnosing condition of track and "speed routing of traffic" on extended sections of road. 5 cl, 2 dwg
