Prediction of Maximum Torsional Wheel-Set Axle Vibrations Considering Non-linear Adhesion Characteristics

Simulation of Torsional Vibration of Driven Railway Wheelsets Respecting the Drive Control Response on the Vibration Excitation in the Wheel-Rail Contact Point

“…At a certain range of slippage (typically at approximately 1 km/h) measurement results start to deviate from Vogel's law. In that case Vogel's law proofed to be more conservative than measurement results [13]. A general definition of the slippage range where Vogel's law is valid, could not be found in literature.…”

“…For the other three, simulation results are slightly more conservative than the measurement results. In addition, Meierhofer et al [13] verified the model of Yu and Breuer by means of an exact time-simulation and state it to be a viable prediction method for maximum dynamic torque.…”

“…Amplitude prediction attempts prepared for the German verification process are the attempts of Vogel [6], Schneider [7], Weinhardt [8] and of Yu/Breuer [9]. Further investigations on the physics of torsional vibration are documented by Liu et al [10], Konowrocki and Szolc [11], Xu et al [12] and Meierhofer et al [13]. In general, the phenomenon of torsional vibration of railway vehicle axles is firstly found to be documented by Körner [14] in the late 80s, when first vehicles with three-phase drive have been developed.…”
