A torsional vibration damper ( ) with an adjustable resonance frequency. The damper has a support plate ( ) arranged on a rotating shaft ( ). A flexural spring arrangement ( ) is mounted on the support plate ( ) with a fixed inner end ( ) and extends radially outwardly to an inertial mass ( ). A support for the flexural spring arrangement ( ) is provided constructed as at least one movable slide element ( ) arranged in a radial guide ( ). A restoring spring ( ) exerts a restoring force on the movable slide element ( ) in a direction opposite to the centrifugal force resulting from rotation of the shaft ( ). The position of the slide element ( ) on the flexural spring ( ) is influenced by the centrifugal force and the restoring force. The magnitude of the restoring force is varied as a function of the rotational speed of the shaft such that the position of the slide element ( ) moves to automatically adapt the resonance frequency of the torsional vibration damper ( ) to the speed of rotation of the shaft ( ).
