| Abstract: | The fatigue damage and failure of steam turbine rotors by torsional vibrations are investigated. Possible causes of the occurrence
of torsional vibrations are discussed. Modeling of torsional vibrations of the shafting of a steam turbine, which occur under
its operating conditions, has been performed, and the cyclic strength of the shafting under these vibrations has been estimated. |
