Friction coefficient in rail-wheel contacts as a function of material and loading parameters

The wheel- rail. contact region is known to have an elliptical form with the axis ratio of about a unit. For a typical load to the wheel of about 50.100 kN and radius 0.5 m, the contact region diameter amounts up to 0.01 m (.Hertzian contact.). The maximum pressure is in the contact center and is about 500 MPa. For a rolling velocity of 50 m/s and characteristic wheel creep values from 2 to 10 %, we obtain typical slip rates in the contact region varying between 1 and 5 m/s.
