Abstract

A device is described for vibration damping, which is attachable on a mechanical structure or integratable therein, having at least one mass which is indirectly or directly operationally linked to the structure via elastic means, referred to as the so-called damper mass, and at least one actuator for changing a stiffness which can be associated with the elastic means. The invention provides an electrical power source, which is capable of generating electrical power exclusively using an oscillating relative movement resulting along the operational link between the damper mass and the structure, and a regulating unit, which is connected to the electrical power source, which activates the at least one actuator as a function of the vibration behavior of the structure based upon a vibration damping rule.
