Abstract

A damping system for damping torsion vibrations of shafts in machines is provided. A torque sensor detects torsion vibrations. A magnetostrictive actuator device creates a mechanical counter-vibration and a control device registers a measurement signal of the torque sensor in a time-resolved manner and creates a phase-shifted signal for a counter-vibration and drives the actuator device. Further, a method for eliminating torsion vibration of shafts in machines with such a damping system is provided. The torsion vibration of the torque of the shaft is registered in a time-resolved manner, a phase-shifted signal is created for a counter-vibration, and a mechanical counter-vibration is created using at a magnetostrictive actuator device.
