Yonago Convention Center BiG SHiP), Yonago, Tottori Japan, Numerical prediction and analysis of the acoustic environment inside of the payload fairing is of crucial importance. The authors have focused on the application of the Wave Based Method (WBM), which is a novel deterministic approach and which has been proposed for numerical predictions up to the mid-frequency range. However, the WBM is only capable of solving models with moderate geometrical complexity for the high computational efficiency. In order to overcome this issue, the hybrid Finite Element-Wave Based approaches have also been proposed. The hybrid approaches combine the advantages of both the WBM and the conventional Finite Element Method (FEM), that is, the high convergence properties of the WBM and no geometrical complexity limitations of the FEM. In this paper, a simple sound transmission model with a structural plate between two anechoic rooms (a source room and a receiving room) is considered, and numerical sound transmission predictions are performed using the 3-dimensional hybrid WB-FE models., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064967004, レポート番号: JAXA-SP-10-012}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {ハイブリッド有限要素-波動ベース法に基づいた音響構造連成解析による音響透過予測}, volume = {JAXA-SP-10-012}, year = {2011} }
