Torsional Dynamics of Power Transmission Systems
The sources of torsional vibration in geared power transmission systems are reviewed. The modal analysis of typical geared systems is described, with useful formulas for natural frequency analysis. Damper design principles are reviewed, with criteria for suppression of troublesome modes. Two Case Histories from practice are discussed, indicating the diagnostic procedure used and the vibration suppression methods in each case.
