Abstrakt

The paper presents a method for effective stress characteristics defining while the evaluation of fatigue toughness is practiced. Correlation between fatigue lifetime, function of spectral density and the exponent of S-N curve is given. The method could be applied in various forms of spectral densities. The analysis of interdependences between dynamic loads, toughness characteristics and the railway structure fatigue life-time is shown on the example of an electric powered train.
