| Abstract: | The dynamic characteristics of overflow of hydropower house structure is discussed with an example of Shuhe hydropower station. A large-scale finite element model of Shuhe hydropower house is built in this paper to calculate the self-vibration characteristics of each part of the hydropower house. Time process analysis is done for the house structure under hydraulic exciting force according to hydraulic experiment data in the surface outlet hole. This research reflects the dynamic response of the house structure and provides the theoretical basis for optimizing the dynamic characteristics of the house structure and improves its design. |
