| 摘要: |
| 结合水消声器的工作原理和水下航行器管路系统及水舱特性,提出了气容水舱消声方法,通过向水舱中充入一定压力和容量的空气,形成蓄能式弹性可压缩扩张室消声容腔,充分利用水下航行器的水舱对通海管路进行消声。对气容水舱消声原理和消声性能进行试验研究,结果表明气容水舱可以有效降低管路出口处的流量和压力脉动,阻断噪声传播通道,降低管路系统水下辐射噪声,为水下航行器水下辐射噪声控制提供了有效方法。 |

| Abstract: |
| By integrating the working principles of water silencers with the pipeline system and water cabin characteristics of underwater vehicles, a gas-water cabin silencing method was proposed. Air with certain pressure and volume was filled into the water cabin to form an accumulator-type elastic-compressive expansion chamber silencing cavity, and the water cabin of the underwater vehicle was fully utilized to silence the sea pipeline. Experimental studies were conducted on the silencing principles and performance of the gas-water cabin. The results show that the flow and pressure pulsation at the pipeline outlet is effectively suppressed by the gas-water cabin, the noise propagation pathway of the pipeline is blocked and the underwater radiation noise of the pipeline system is reduced. This gas-water cabin provides a usefully approach on underwater radiation noise reduction of underwater vehicle. |
