摘　　要：运用统计能量分析方法,推导出加筋结构声传输函数,采用VA One中SEA模块对加筋铝板声传输损失进行研究,建立加筋铝板隔声计算的仿真模型。将仿真结果与已有文献试验数据进行比较,证明了采用加筋结构声传输计算模型研究其隔声特性的有效性并分析了相关参数对加筋铝板声传输的影响。研究结论为船舶加筋板的隔声设计提供了一定参考,尤其对铝合金上层建筑舱壁和围壁隔声护板的声学设计具有指导意义。Sound transmission function of stiffened structure was deducted by statistical energy analysis（SEA） method.Sound transmission lost of stiffened aluminum plate was investigated by SEA module of VA One software and a general simulation model for calculating sound insulation of stiffened plate was established.The simulation results were compared with experiments data from literatures.The validity of simulation model was verified while stiffened aluminum plate was adopted to investigate sound insulation.The influence of related parameters on sound transmission lost of stiffened aluminum plate was also studied based on the front principle.The research provides references for the design of sound insulation about stiffened plates,especially bulkhead of aluminum superstructure and insulation apron of bulkhead.
