Influence of Self-Vibration Characteristics of Pump Station Considering Liquid-Solid Coupling

摘要：

Considering the contacts between solid and fluid are subjected to dynamic lodes, the influence of vibration characteristic of structure which is coupled with solid and fluid are applied to calculation. In this paper, the calculation formula of structure vibration between solid mass and fluid is derived and the finite element method (FEM) is adopted for discrete of pump station structure and fluid, considering the effect of fluid flow to solid structure, the natural frequency of pump station is acquired. The result shows the method is correct and reasonable.
