| Abstract(J) | 本研究では，簡易ラゲッジ空間模型を分析対象にCAE固有モードと実稼働TPA主成分モードを連携させることで後席位置に設定した応答点音圧に対するラゲッジ空間の高寄与音響モードを把握する．さらに対策周波数周辺のCAEモード応答をTPAモデルに導入することでラゲッジ形状変更時の応答予測手法も検討した． Translation |
| Abstract(E) | In this study, a method for obtaining high contributing acoustic mode in a vehicle luggage compartment model to the response sound pressure at the rear seat position was proposed by combining CAE eigenvalue analysis and OTPA principal component model. In addition, a response point SPL estimation procedure after the luggage space modification was also considered by introducing principal CAE acoustic mode response into the TPA model at around the target frequency band. |
