Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

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.
