| 摘 要： | 本文研究了声障板相关参数对球鼻艏导流罩内声纳艉部声场的影响。对某舰缩比模型罩建立了有限元模型，然后运用有限元法声学分析软件，计算了某些频率下声源定向发射的声衰减特性和声场特性。计算结果与已进行的模型罩消声水池的试验结果吻合良好。

| Abstract: | The paper investigates the influence of acoustical baffle parameters of spheroidal sonar dome on bow on the afterbody sound filed by building a reduced scaled FEM model of the sonar and the fairing. Then, it calculates acoustical performance and acoustical reducing features of different acoustical baffles when acoustics source launches directly. The results of calculation simulation has good consistency with the experiment ones and some useful conclusions are obtained. |
