Effect of Curve Radius on Rolling Contact Fatigue Properties of Rails

  • The effect of curve radius on the rolling contact fatigue properties of PD3 and U71Mn rails was investigated on JD-1 wheel/rail simulation facility with different attack angles.The results indicate that with a decrease in curve radius the wear volume of rail roller increases,and the plastic flow layer becomes thicker and uneven.PD3 rail has higher wear resistance,but lower fatigue resistance,than U71Mn rail does.U71Mn rail shows an excellent anti-fatigue property.
