| Abstract: | Prototype vibrations were tested for a generator set and hydropower house on Lancangjiang River in Yunnan.Their mechanism is analyzed in this paper and they are evaluated by the corresponding rules.The features of vibration sources and propagation paths are examined,and a finite-element method is used to compute the dynamic responses of the power house.Some suggestions for operation safety and vibration control are given. |
