Sensitivity analysis of torsional vibration behavior of the shafting of a turbo generator set to changes of its mechanical parameters

Abstract

Aiming at a 300 MW turbo-generator model, the sensitivity of natural torsional frequencies and modes of torsional vibration (TV) to the rotational inertia and stiffness of the turbo-generator were analyzed. Calculation results show
