ABSTRACT:
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. The energy exchanging device is capable of imparting a plurality of successive torsional impulses to the member. A suitable sensor, such as an angular amplitude sensor or a torsional stress sensor, is utilized to detect the presence of a resonance torsional vibration in the member. A computer is in communication with the energy exchanging device and the sensor, and is capable of controlling the energy exchanging device.
