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.
Claims5
A method, comprising:
- determining a first resonant frequency of a system comprising a vibratory body, a supporting body and a vibration damping device disposed therebetween having first and second fluid filled chambers not in communication with each other;
- and
- damping vibrations at said first resonant frequency in a system comprising a vibratory body, a supporting body and a vibration damping device disposed therebetween having first and second chambers which communicate with each other through a passage configured to impart a second resonant frequency to fluid received within said passage which substantially equals said first resonant frequency.
