摘要
Abstract
In response to the vibration problem of a vertical axial flow pump station caused by water,a modal analysis method based on fluid-structure coupling is adopted to analyze the mode of a certain vertical axial flow pump station under the action of water,and then analyze the stress and deformation of the pump station under the action of water.It was shown that modal analysis based on fluid-structure coupling can accurately reflect the pump station mode under the action of internal water bodies;It was found that under the coupling effect of water bodies,the impact of water bodies on the pump station structure is mainly concentrated at the concrete structure of the outer wall of the flow channel,with a greater impact on the deformation of the upper floor slab and the concrete structure of the descending section of the outlet flow channel hump,and a smaller impact on the overall structure of the pump station.关键词
