Abstract

See full text

A vibration damping system comprises a vibration applying device mounted on a frame and a control device that controls the vibration applying device, the control device comprising a voltage command producing part that produces a driving voltage command to drive the vibration applying device and a vibration failure diagnosis part that diagnoses whether there is failure based on a vibration detection signal output by a vibration detecting device, wherein the voltage command producing part produces the driving voltage command corresponding to a diagnosis frequency that is previously set at a frequency identical to a resonance frequency of the frame or the vibration applying device or at a predetermined frequency close to the resonance frequency and makes the vibration applying device generate the vibration applying force according to the driving voltage command, and the vibration failure diagnosis part diagnoses whether there is failure based on the vibration detection signal.
