Paper Title:
Correction on Parameters in Torsion Vibration Model for Turbine-Generator Shafts
  Abstract

The accuracy of parameters in model has important influence on torsion vibration analysis of turbo-generator shafts. In this paper, a method for torsion vibration response calculation based on multistage lumped mass model is introduced. A method for identification and correction on stiffness and damping in torsion vibration monitoring is put forward. Pre-revision on shaft stiffness is realized through analytic calculation of the temperature distribution of turbine-generator shafts. The difference of natural frequencies and response of torsion vibration of shafts are calculated and analyzed after parameter correction, which offers the reference for studying torsion vibration fatigue of shafts.
