SEA response analysis using FEM considered coupling in damping for four panels with damping layers combined in cross shape

Abstract

This report is about proposal of Statistical Energy Analysis (SEA) response analysis of four panels with visoelastic damping layers connected in cross shape. We use FEM and Modal Strain Energy (MSE) method to identify internal loss factors. As a result, we could identify SEA parameters in high precision. And the proposed SEA enables us to improve precision in low frequency. Moreover, compere results of the SEA method and results of direct calculated FEM, was mostly in agreement.
