摘要:
针对由水体引发的立式轴流泵站泵房振动问题,采用基于流固耦合的模态分析方法,对水体作用下的某立式轴流泵站泵房模态进行分析,进而分析泵房在水体作用下的应力和变形情况。研究表明,基于流固耦合的模态分析可以较确切的反应内部水体作用下的泵房模态;发现在水体的耦合作用下,水体对于泵房结构的影响主要集中在流道外壁混凝土结构处,对出水流道驼峰上部楼板以及下降段混凝土结构的变形影响较大,对于泵房整体结构影响较小。
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.
