摘　　要：水轮发电机组轴系的固有频率计算是振动研究的一个重要内容。针对三峡水轮发电机转子轴系,将其分解为数个单元,分别运用传递矩阵法和有限元法进行了编程计算,得到了其固有频率数值;随后分别研究了电磁刚度、附加水质量和陀螺效应对系统固有频率数值的影响规律。The calculation of the natural frequency of the hydro-power generating set ＇s shafting is an important part of the study of vibration. The authors of this paper obtain the natural frequen-cy of the hydro-power generating set ＇s shafting of the Three Gorges by breaking down it into sev-eral units, make respective calculations with the transfer matrix method and the finite element method, and then study the laws for the effect of electromagnetic stiffness, added water quality; gyroscopic effect on the natural frequency of the system.
