Method and device for influencing the transfer of vibrations of a vibration generator to an object connected to it, in particular of engine vibrations to the body of a motor vehicle

A method and a device for influencing the transfer of vibrations of a vibration generator to an object connected to it, in particular of engine vibrations to the body of a motor vehicle. At least one piezo element is arranged as an actuator in the region of an intermediate element connecting the vibration generator to the object. Primary vibrations are transferred between the vibration generator and the object via the intermediate element. The actuator is induced in a controlled manner to undergo secondary vibrations. The total energy and/or the composition of the frequencies of the vibrations transferred via the intermediate element are changed by the actuator, and the remaining residual vibration is measured and used for controlling the secondary vibrations. Surprisingly good results are achieved in this way if the secondary vibrations are introduced in the region between the vibration generator and the intermediate element and if the residual vibration is measured in the region between the intermediate element and the point at which the intermediate element bears against the object.
