The purpose of the work is to study the main parameters of energy dissipation in metals under periodic loads in order to detect fatigue cracks in the metal structures of railway bridges. The method of research is the method of infrared thermography. The objects of study are fatigue cracks. Dynamic tests of a beam with a fatigue crack in the loading ranges corresponding to real loading of span structures in terms of frequencies and amplitudes of oscillations were carried out. To study the influence of measurement conditions, measurements were taken at different distances from the infrared detector to the beam surface, with different recording lengths corresponding to the train passing time over the bridge, at different frequencies and oscillation amplitudes. For processing thermograms, a special technique and software are developed. As a result of the study, it was established that in all loading modes, the tip of the fatigue crack, which has an increased heat emission compared with the surrounding surface of the beam, is recognized uniquely and confidently by infrared thermography. With short recordings, the influence of environmental conditions is minimized. The developed method of processing thermograms, based on the integration of temperature increments under cyclic loading, makes it possible to completely eliminate the influence of extraneous factors.
