Throughout the homologation process, especially in Germany, the torsional load acting on the wheelset due to drive train oscillations must be evaluated. The maximum values of these dynamic torsional moments are strongly influenced by the adhesion conditions in the wheel/rail contact and the slip velocity range between wheel and rail due to drive control dynamics. The adhesion conditions are hard to measure and to reproduce. Hence, it is time-consuming to prove that the measured dynamic moments cover the possible maximal values. The proposed energy method allows a proper prediction of maximum dynamic moments, assuming critical adhesion conditions and an appropriate drive train model. The criticality of the adhesion conditions is shown by measurements. The method is applied to different types of drive train. The predicted maximum values of the dynamic moments are compared with measurement results. During the drive control design phase, the energy method helps to determine a setting range of the slip velocity compatible with the wheelset axle strength. In the homologation process the method could replace measurements.
