摘要
对水轮发电机组轴向振动机理进行研究,将机组轴向振动分解成转子与转轮组成的弹簧系统的轴向振动和机组主轴的轴向振动2个系统.用数学方法导出2个系统轴向振动方程并解出振动方程.
The axial vibration of water-turbine generator units is divided into two components: the one is the axial vibration of the spring system consisting of rotors and runners, and the other is the axial vibration of the main axis of generator units. The axial vibration equations of the two systems are derived, and their solutions are obtained by the numerical method.
