The study of the fatigue of mechanical systems is of great importance to reserve their
safety. The present research work is dedicated to the study of the phenomenon of
fatigue damage of the bogie of the railcar, following the premature appearance of
cracks in the axis of the axle. The Ansys software is used for modeling the digital
model which is based on the finite element method. The predictive model obtained
made it possible to highlight, under different cyclic loadings, the factors influencing
the propagation of cracks and their impacts on the lifetime of the system.
