| Abstract: | Pumped storage power station has the characteristics of high water head,large capacity and fast speed,which causes the vibration problem especially prominent.Strong vibration will cause damage to units and weak structure of the power house,and affect safe and stable operation of power station.Combined with a pumped storage power station,this paper analyzes the vibration sources that may resonate with the plant structure,studies the influence of boundary conditions and material characteristics on the natural vibration characteristics of the structure,and analyzes the dynamic response law of various parts of the plant under the dynamic load of the unit in combination with viscoelastic artificial boundary conditions. |
