| Abstract: | The coupling problem betwwen bending and torsional vibration in turbine generator shaft system has been put forward in this paper. The vibration equations, which contain coupling effect of bending and torsional vibration, have been established for the simplified model with lumped parameters. The coupling mechanism has been elaborated and the reality of coupling in turbine generator vibration has been stated. Finally, anumerical illustration has been given. |
