Abstract: Abstract The wear and rolling contact fatigue of wheel-rail materials were investigated through varying wheel/rail hardness ratios (Hw/Hr) and creepages. The results indicated that with the Hw/Hr increasing from 0.927 to 1.218, the wheel wear… read more here.

Abstract: This study focuses mainly on the mechanism of wheelset longitudinal dynamics which has often been neglected. By analysing the process of wheel/rail rolling contact, taking into account of the wheelset longitudinal vibration, a wheel/rail longitudinal… read more here.
