潜艇管路系统振动噪声控制技术的现状与发展

当螺旋桨噪声、水动力噪声和设备机座机械噪声被有效抑制后,管路系统便成了"安静型"潜艇的主要噪声源,有效控制管路系统振动噪声是潜艇实现安静化的重要环节。主要介绍了振动噪声被动控制和主动控制在潜艇管路系统中的研究进展,针对振动噪声被动控制措施在低频场控制中存在的不足,以及主动控制技术的快速发展,探讨了未来潜艇管路系统振动噪声控制的发展趋势,提出了一些建议,以期为提高我国潜艇隐身性能提供一定的借鉴作用。

Review of vibration and noise control technology in piping system for submarines

When propeller noise,hydrodynamic noise and machinery noise of facility base are controlled effectively,then the piping system becomes the main noise resource for quite submarine,so the important step for a submarine to realize silence is the control of piping system noise.In this paper,the current status of vibration and noise control is discussed from the two aspects of passive control and active control of piping system for submarines.According to the deficienties of the passive vibration and noise reduction measures in low-frequency field and the rapid developments of the active controlling technologies,the developed trend to the vibration and noise control of piping system for submarines in the future are discussed.At last,some advice is put forward,so offer some references for improving the submarine,s acoustic stealth performances.
