Abstract

The invention relates to a drive train (1) of a turbo engine, which can be driven by a variable or constant torque and which has at least one configurationally determined natural torsional frequency, which drive train is excited during the actuation by an external excitation having a variable excitation frequency. According to the invention, the at least one natural torsional frequency of the drive train (1) is modified when the excitation frequency of the external excitation approximates the at least one natural torsional frequency of the drive train (1).
