| Abstract: | In the main line transporting both passenger and freight with notable damage of contact fatigue,the paving trial of 1 100 MPa heat treated rail,U75V rail,and U71Mn rail have been carried out.The result indicates that the 1 100 MPa heat treated rail's contact fatigue resistance properties are better than the U75V and U71Mn rail's.Selecting 1 100 MPa heat treated rail in the sweeping curve or line of the main line transporting both passenger and freight with notable damage of contact fatigue,the rail's contac... |
