| Abstract: | A program for computation of the transverse self-oscillation characteristics of the hydrogenerator set is implemented. The finite element method with consideration of gyroscopic effect is used in this program. The transverse self-oscillation characteristics of the shaft system of the Hong Shi hydrogenerator set in Ji Lin Province is computed. Curves of processing speed to several factors are given, sensitivity of processing speed to those factors is analyzed. The cause of the vibration fault and design shortcoming of this hydrogenerator set is pointed out. |
