| Abstract(J) | LBMを用いた流れによる室内騒音の予測システムを開発し、その解析精度を分解法を用いた実験結果や従来法と比較検証した。加振力を波数周波数スペクトル解析により流体成分と音響成分に分解し、構造振動と車室モデル内放射騒音のそれぞれの寄与を調べた。 Translation |
| Abstract(E) | A prediction system for flow-induced interior noise by using LBM has been developed and the accuracy of the analysis has been verified with the results of experiments and conventional methods using the decomposition methods. The excitation force is decomposed into fluid and acoustic components with wavenumber frequency spectrum analysis, and their respective contributions to structural vibration and interior acoustic emissions are investigated. |
