The FEM Analysis of Coupled Vibration of the Elastics Baffle with two Sides’ Fluid in a Rigid Tank
Authors: , ,
Abstract: The coupled vibration of the elastics baffle with two sides’ fluid, in a rigid tank, is carried out by FEM. Under the special boundary conditions, the equations of coupled vibration are derived in the form of pressure and displacement, which include the elementary matrix on mass, stiffness and coupled domain. It regards the structure and fluid element global degrees of freedoms as row index and column index, and the coupled matrix is assembled to the global matrix. Finally, the numerical results obtained with the proposed FEM are compared with the test example, which agree well.
