<p>Provided is a low-cost active vibration damping device with which vibration can be reduced in a device for which the influence of vibration must be eliminated. This vibration damping device, which is attached to a structure for which vibration must be reduced, is characterized by being equipped with multiple identical vibration detection means that detect distortion at a portion of the subject structure, multiple identical vibration generation means that generate distortion at a different portion of the subject structure, and a control means that, on the basis of signals from the vibration detection means, generates a control signal that sets the driving force of the vibration generation means, with the condition of the control signal for setting the driving force of the vibration generation means being changed with respect to changes in the frequency and magnitude of the vibration of the subject as detected by the vibration detection means.</p> |
