A piezo-based device is attached or otherwise mounted on a driveshaft tube or other component of a drive train assembly for reducing the amount of vibrations that are generated therein during operation.. The piezo-based device is used to dampen these vibrations by converting the physical vibratory motion of the driveshaft tube into an electrical current that is dissipated through a resistive element as heat. By varying the magnitude of the resistive element, the center dampening frequency of the piezo-based device can be varied as needed for the particular driveshaft tube and the drive train assembly. If desired, an inductive element may be provided with the resistive element to dissipate the electrical current. The magnitude of the resistive element may be varied by a controller in response to the magnitude and/or frequency of the vibrations sensed by a sensor. Alternatively, the stiffness of the piezo-based device may be controlled by an electrical current generator that can be operated by a controller in response to the magnitude and/or frequency of the vibrations sensed by a sensor. The piezo-based device may be mounted on either an exterior or interior surface of the driveshaft tube. Alternatively, the piezo-based device may be embedded within or formed integrally with the driveshaft tube. If desired, a plurality of such piezo-based devices may be provided on the driveshaft tube.
