摘　　要：提出了汽轮发电机组轴系弯曲和扭转振动耦合问题。针对具有集中参数的简化轴系模型，建立了考虑弯曲和扭转耦合效应的振动方程，初步阐述了弯扭耦合的作用机理，论证了机组轴系耦合作用的存在性。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.
