| 中文摘要: |
| 本文研究内容属于舰艇声兼容性技术研究的一部分。应用声学软件SYSNOISE计算了,声纳定向发射时某试验用声纳导流罩及尾部吸声障板的声场特性,同时进行相同工况的水下模型试验。计算结果与试验结果吻合良好,说明应用声学软件对声纳声场进行计算是一种可行的方法,有可能推广至其他的水下模型的声场计算。结果数据反映了吸声障板对声纳定向发射时声场的影响,为舰艇总体声纳导流罩内吸声障板的结构设计、声兼容设计提供依据。 |
| 英文摘要: |
| The paper is a part of the ship noise compatibility. It calculates by using acoustic software SYSNOISE the acoustic performance of the acoustical baffle in ship sonar hosing when the acoustic source launches directly. Then, the underwater model is test in the same condition. The calculation results are in good agreement with the experimental. Therefore, it seems feasible to use the acoustic software to calculate the sound field of sonar, and this calculation method may be extended to the sound field of other underwater models. The data reflect the effects of the acoustical baffle when the sonar launches directly, and provide basis for construction design and acoustics compatibility technique of the acoustical baffle in sonar housing. |
