| 摘 要： | 管路噪声是舰艇低频噪声的重要来源之一,严重影响舰艇的声隐身性能。针对舰艇中典型的离心泵组,设计蓄能器和亥姆赫兹消声器相结合的低噪声排水装置。通过AMESim软件建立仿真模型,并搭建实验平台进行验证。仿真和实验结果均表明,低噪声排水装置可以有效衰减离心泵出口管道中的压力脉动,从而降低流体噪声和管路振动。

| Abstract: | Pipeline noise is one of the important source of low frequency noise of battleship, which has serious impact on the acoustic stealth performance. Aimed at typical centrifugal pump, design a low noise drainage device, which combines accumulator and Herm hertz muffler. Build simulation model by software AMESim, and verify the result by experiment. Simulation and experiment results show that low noise drainage device can effectively attenuation the pressure pulsation of pipeline of centrifugal pump, so as to release the fluid noise and pipeline vibration. |
