Self-excited torsional wheel-set axle vibrations can lead to polygonization of wheels, cause discomfort for the passengers, and can lead to issues with the stability of the press-fit between wheel and wheel-set. To predict their amplitude, three different methods were investigated: a time-simulation for reference, an energy-method, and the 2cx-hypothesis. It was found that the 2cx-hypothesis shows significant deviations. The energy-method is very accurate (deviations smaller than 0.5%) while still significantly faster than the time-simulation. Thus, the energy method is a viable alternative to predict the amplitude of these vibrations.
