摘要
针对充液管路系统低频线谱噪声控制问题,设计1套充液管路噪声主动控制系统并进行试验验证。在循环水管路试验平台上开展不同工况下的多线谱噪声有源控制试验,验证有源消声系统的降噪性能。试验结果表明,该系统可实现低频线谱噪声的有效控制,在管内可以取得10 dB以上的降噪效果,系统具有良好的鲁棒性。试验结果可以为舰船管路系统噪声主动控制提供切实有效的依据。
Aiming at the problem of low frequency line spectrum noise control in liquid filled pipeline system,a set of active noise control system for liquid filled pipeline is designed and tested.Multi line spectrum noise active control tests under different working conditions are carried out on the circulating water pipeline test platform to verify the noise reduction performance of the active noise reduction system.The results show that the low-frequency line-spectrum noise can effectively be reduced in the control system.The noise attenuation of over 10 dB is achieved in liquid-filled pipe system.In addition,the robustness of the ANC system is very well.The test results can provide effective basis for active noise control of ship pipeline system.
