制振ビードパネルを十字結合した構造における減衰の連成を考慮したFEM援用SEA応答解析

抄録

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.
