Abstract (en)
[origin: WO2010091904A1] The invention relates to a damping system for damping the torsion vibrations of shafts (1) in machines, wherein there is a torque sensor (5) for registering the torsion vibrations; there is at least one magnetostrictive actuator device (3, 4) for creating a mechanical counter-vibration and there is a control means that registers the measurement signal of the torque sensor (5) in a time-resolved manner and creates a phase-shifted signal for a counter-vibration and drives the actuator device (3, 4). The invention further relates to a method for eliminating torsion vibrations of shafts (1) in machines having said damping system according to the invention: the torsion vibration (dMA) of the torque (MA) of the shaft (1) 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 least one magnetostrictive actuator device (3, 4).
