DEVELOPMENT OF PERIODIC PROFILE DISTURBANCES IN RAILS ('ROARING RAILS')

ZUR ENTWICKLUNG PERIODISCHER PROFILSTOERUNGEN AN EISENBAHNSCHIENEN

A simple model is presented which yields local, complex eigenvalues whose frequency-dependent course helps to assess the susceptibility of a system to corrugation ('roaring rails'). The only wear mechanism considered in the model is wear due to friction; changes in the surface material and plastic deformation are not taken into account. The model was extended to consider the initial condition of the rail profile, for which the wheel/rail system acts as a filter. This way, the rail profile can be calculated as a function of the number of train movements. An analysis of the experimental findings shows that the assumptions on corrugation susceptibility of a system on the basis of the local eigenvalue curves are not transferable without modifications.
