【Abstract】 Vibration is the main accident that affects the normal function of hydrogenerator unit and endangers the life span of hydrogenerator unit. To eliminate the vibration accident of the unit, it is necessary to detect the causes that lead to the vibration of the unit. This paper intends to discuss the causes resulting in the vibration of the unit, revealed by some characteristics of the unit vibration. For the sake of simplifying the program, the interaction of the factors causing the vibration of the unit was not considered in this paper. However, it is helpful for the analysis of the main reasons of the unit vibration.更多还原
