High speed wheelsets of railway systems differ from classical ones. The dynamics are determined by gyroscopic and inertia moments. A dynamical model with 40-DOF was generated using elastic beam elements to describe the axle, connected to rigid wheel and brake disks. Imbalance calculations and wear simulations were carried out resulting in polygonalization of the circular wheel surface. Even when starting the simulation with wheels of constant radius, the unroundness grows to unacceptable values.
