| 摘 要： | 针对某舰壳声纳和导流罩,运用有限元建模计算软件,对1:1实罩建立有限元模型,然后运用声学分析软件,计算某些频率下声源定向发射时的相关数据,主要是水平中性面和垂直中性面的波束宽度变化率和波束高度变化率以及左、右旁瓣高度,结果说明导流罩内加有障板对其声场特性的影响。

| Abstract: | Aiming at hull sonar and bossing of a ship, the paper uses finite element modeling and calculating software to establish a full scale finite element model of bossing, then brought to bear acoustic analysis software, calculated the correlation data with certain frequency while sound source directional transmission, mostly was the rate of change of beam-width and beam-height in horizontal and vertical neutral surface ,and the height of left and right side lobe. The results indicated the affection of adding baffle in bossing to its sound field characteristics. |
