A torsional vibrations problem

Electrical Engineering, 1958
TORSIONAL vibration studies of simple mechanical systems are usually handled by methods which, while not difficult, often require the expenditure of considerable time when done by hand. The use of a digital computer shortens the time considerably. One method frequently used is the Holzer table calculations resulting in the determination of the natural ...

Active torsional vibration damper

The Journal of the Acoustical Society of America, 1997
A resonance torsional vibration damping system includes a member having at least one node location along its length. An energy exchanging device, such as a fly wheel and eddy current brake, is operably connected to the member at a damping location that is a distance away from the at least one node location.
