Damping system and method for eliminating torsion vibrations

A damping system for eliminating torsion vibrations of a shaft of a machine, comprising:

• a torque sensor for detecting torsion vibration;
• a holder device;
• a first magnetostrictive actuator device for generating a mechanical counter-vibration, wherein the first magnetostrictive actuator device comprises at least one electromagnetic coil arranged on the holder device;
• and
• a control unit which
• detects a measurement signal of the torque sensor in a time-resolved manner,
• generates a phase-offset signal for the counter-vibration, and
• drives the magnetostrictive actuator device,
• wherein the machine comprises a housing, wherein the holder device is
• anchored on the housing or
• arranged on the housing and coupled to an oscillating movement of the shaft caused by imbalance and/or rotation imprecision and/or bearing tolerances and/or torsion.
