Analysis of rail milling as a rail maintenance process: Simulations and experiments

The maintenance process rail milling and the rolling contact behavior of a milled rail are analyzed in detail. By using commercial finite element programs the milling process and the rolling-sliding contact of a wheel on a milled rail are simulated with 3D and 2D methods. These results are compared to experimental results and metallographic investigations of a milled rail after an actual milling process and after milling tests that were done in...
