Influence of Extension of Load Spectrum on Estimation of ResidualnFatigue Lifetime of Railway Axle
Original language description
Railway axles are subjected to cyclic amplitude loading which can lead to fatigue failure.nFor safe operation of railway axles a damage tolerance approach taking into account a possiblendefect in railway axle is often required. Because of different operation regimes of trains (fast/slownride, ride on straight track, on curved track, over switches etc.) the load amplitude of axle is notnconstant. The variability of load is defined by a load spectrum, which is determined experimentallynby measuring of load in service conditions. Even though the load spectrum is measured on severalnhundreds or thousands of operation kilometres, the railway axles are in operation much longer timen(often tens of years). Therefore, some load amplitudes higher than ones measured in the test cannoccur during a long-term axle service. The contribution presented deals with the effect of extensionnof load spectrum by rare high load amplitudes, which can occur during long-term operation, onnresidual fatigue lifetime of railway axles.
