| 摘 要： | 为了更准确地预报舱室噪声,以驳船为例,建立船舶SEA模型,采用VA ONE软件分析SEA参数的取值对于噪声预报结果的影响。首先分析钢结构内损耗因子和壁面吸声系数对舱室噪声预报结果的影响,其次分析了发电机组的噪声激励对舱室噪声产生的影响,得出了钢结构内损耗因子对于噪声预报结果影响较大、壁面吸声系数对于噪声影响较小的结论。为后续建立SEA模型时参数的选取提供了参考依据,具有一定的工程实用价值。

| Abstract: | In order to predict cabin noise more accurately,taking barge as an example,a ship SEA model is established,and the influence of SEA parameters on noise prediction results is analyzed by using VA ONE software.Firstly,analyzing the influence of choosing different damping loss factors and absorption coefficients on the prediction of cabin noise.Secondly,the influence of the noise excitation of the generator set on the cabin noise is analyzed.It is concluded that damping loss factor of the steel structure has a greater influence on the prediction of cabin noise.The absorption coefficient has less influence on the prediction of cabin noise.It provides a reference for the selection of parameters in the establishment of SEA model,and has engineering practical value. |
