| 摘 要： | 以某一船艇机舱为例,从机舱发动机表面振动声辐射着手,建立了机舱的统计能量分析(SEA)模型,对船艇机舱的进行了仿真计算。结果表明,统计能量分析法与实际测量值吻合,SEA模型的计算值与舱内声压水平实测值误差在主要频带达到3dB以内。

| Abstract: | Taking a ship engine compartment as example, a model has been established based on statistical energy analysis ( SEA). By taking into account the vibration-sound radiation of the engine surface, a simulation program is designed with the aid of rigorous acoustical theory as well as the proper technique applied in statistical energy analysis. As a result, the calculation value of engine compartment noise level reduces a difference of less than 3dB compared to the test data in main frequency. |
