摘要
低频线谱噪声是船舶的“声指纹”特征,影响船舶的隐蔽性,而主动控制技术是抑制船舶低频线谱振动噪声的重要方法。为此,首先简要介绍了船舶低频线谱噪声的主要传递路径;然后,从船舶机械主被动隔振技术、船舶管路噪声主动控制技术、船舶推进轴系纵向和横向振动控制技术等方面,综述了近年来船舶振动与噪声主动控制技术的国内外研究进展和应用情况,梳理了技术应用的难点,对技术发展趋势进行了展望。
Ship low-frequency line spectrum noise,known as the"sound fingerprint",affects the abi-lity of ship concealment.Active control technology is an important method to suppress the low-frequency line spectrum vibration and noise.For this reason,the main transmission path of the low-frequency line spectrum noise on ship was briefly introduced,and then the research and application of the active control technology on ship vibration and noise both at home and abroad in recent years were reviewed,the difficulties in application of the technology,and finally looks forward into the development trends were summarized.Based on such technological means as the active-passive vibration isolation of ship machinery,the active control of ship pipeline noise,and the longitudinal as well as transverse vibration control of ship propulsion shaft system.
