The peeling near the fillet on the working edge of the steel rail head is mainly caused by the following three reasons: the peeling is caused by the longitudinal fatigue crack caused by the inclusion or the contact shear stress; the shear stress alternating cycle caused by the guide wheel on the curved outer steel rail promotes the rail Fatigue of the outer steel rail head leads to peeling; poor maintenance of wheels and steel rail accelerates the development of peeling. Usually peeling will cause stress concentration in the notch area and affect the ride comfort, increase the dynamic impact, and promote the generation and development of cracks in the notch area.
