Influence of Material Properties on Modal Characteristics for Fluid-Structure Coupled Vibration System

Abstract:

The analysis processing for the linear coupled vibration of a flume and its inner fluid often uses FEM method. An equation set which contained the fluid node pressure and the structure node displacement is formed, based on this equation, reduction form and symmetry form is used to get the same modal frequency. Computers can calculate out the frequency more rapidly by a smaller control equation. According to the frequency comparison of different fluid-structure coupled vibration system with different materials, this paper draws some conclusions on the influence of material properties on modal characteristics for fluid-structure coupled vibration system. It can give a reference to select the material in practical engineer.
