Study on Fluid-Solid Coupling for Vibration Characteristics of Stiffened Plate

Abstract:

In this paper, the vibration characteristics of plate and stiffened plate in the flow field are calculated by employing fluid-solid coupling method. The wet-frequency and wet-mode numerical computing results are analyzed. The influence of boundary condition, edge length ratio and depth of water on wet mode and wet frequency are studied. A mixed finite element-boundary element method is adopted in the numerical calculation, which makes the added water mass matrix calculation be limited to the liquid-solid interface. Thereby, the calculated amount is significantly reduced and the calculation efficiency is increased.
