| Abstract: | According to the structure characteristics of a turbo generator rotor shaft system,a torsional vibration model of a large size rotor shaft system with an elastic distributed structure has been established,and the torsional vibration wave equation under the different boundary and initial conditions as well as the impact of the damp of each shaft has been deduced.In the meanwhile,the inherent characteristics of a 300 MW turbo generator rotor system is studied analytically and calculate with analytical methods. |
