Procedure and device to influence the transmission of vibrations of a vibrating element to a unit connected thereto, in particular of engine vibrations to the body of a vehicle

摘要

The invention relates to a method and a device for influencing the transmission of vibrations of a vibrator (6) to an associated object (1), in particular of motor vibrations to the bodywork of a motor vehicle, connected in the region of the vibrator (6) with the object the intermediate element (4) at least one piezo element is arranged as an actuator (5), wherein transferred via the intermediate element primary vibration between the vibrator and the object, wherein the actuator is controlled energized to secondary vibrations, and wherein the actuator of the total energy / is changed or the composition of the frequencies transmitted via the intermediate member vibrations and the remaining un-oscillation measured for controlling the secondary vibrations used. Surprisingly good results are achieved in this case by the fact when the secondary vibrations in the area between the vibrator and the intermediate member are introduced, and when the residual vibration is measured in the region between the intermediate member and the abutment of the intermediate member and the object.
