Influence of Normal Force and Tangential Braking Force on the Fatigue Damage

Wen Zhong, Wei Qin, Guo Jun & Qiyue Liu

Abstract


The rolling tests of railway rail were performed using a JD-1 wheel/rail simulation facility without any lubricant. The failure
behavior of rail rollers with different materials was investigated in detail by examining wear volume and wear scar using
optical microscopy (OM) and scanning electronic microscopy (SEM). The results indicate that with the increase of the
normal forc and Tangential Braking Force e, the wear of rail increases, and the rail presents obvious plastic flow.
