| Abstract: | The formation mechanism of fatigue crack initiation and fatigue crack propagation under rolling contact was analyzed. The classification of rail rolling contact fatigue and the influence factor of contact fatigue were introduced. Some measures were put forward to reduce rail rolling contact fatigue from the development of new rail material, the optimization of rail contact geometry surface and the improvement of rail working condition. |
