Rotor Dynamics and Irregular Wear of Elastic Wheelsetsoning noise. The reason of this unpleasant phenomenon is the development of out-of-round wheels. This paper will discuss the influence of initial out-of-roundness of wheels as well as the influence of wheelset unbalances at high speeds on this wear process. Using a modular approach the model of the

On the Numerical Analysis of the Wheel-Rail System in Rolling Contactroach. The presented paper gives an overview over the theoretical background of the Arbitrary Lagrangian-Eulerian formulation of the stationary dynamics of rolling bodies in elastic-elastic contact. Contact formulations for dynamic contact conditions are developed using a velocity oriented approach.

Experimental Analysis of the Cyclic Deformation and Damage Behavior of Characteristic Wheel and Railc (TEM) investigations of the microstructure of a cyclic loaded rail steel and the deformation and lifetime behavior of a cyclic loaded wheel steel are represented. For the TEM investigations specimens are worked out of the head of unused rails. With these specimens push-pull tests under several loa
