Analysis on coupling system of fluids and aqueduct water bridge base on FSI method

Abstract

   The analysis fluid structure interaction (FSI) have been attracted many researchers in the recent years.FSI method becomes a crucial consideration in the design and analysis of various engineering field.FSI allow to replaces the traditional method of assign load on structure by the way that the block ofwater can act directly on structure over time. However, the coordination of FSI is a difficult problemsince the coordinate system which used in describing block of water and the structure is not uniform. Inthis research using FSI method with a help of ADINA software to solve the problem of fluid andaqueduct interaction for obtained the displacement and stress of structure duration time of earthquake.Due to the influence of earthquake motivation, the static traditional analytical method cannotaccurately simulation thus more attention is paid to the FSI method. Other important task of this studyis the characteristic of hydrodynamic pressure of flow influence by earthquake can be simplified inexpression as mathematical equation based on the relationship of the water depth, the acceleration. Theresearch of FSI can further apply on dynamic response of water resource such the spin-way or dam,turbine in the hydropower.
