Abstract
The method comprises determining a first resonant frequency of a system comprising a vibratory body, a supporting body and a vibration damping device disposed therebetween. Vibrations at the first resonant frequency are dampened by defining first and second chambers in the device which are separate from each other and communicate with each other through a passage configured to impart a second resonant frequency to fluid received within the passage which substantially equals the first resonant frequency.
