摘要

舰船管路系统的低频振动和噪声控制问题是当前舰船设计和制造中亟待解决的重难点问题和研究热点.浅析了舰船管路系统振动与噪声产生的原因,综述了国内外管路系统减振降噪治理技术,指出当前振动和噪声控制技术中存在的瓶颈问题,结合近年来凝聚态物理领域新兴的声子晶体减振降噪研究,提出利用声子晶体周期结构设计技术解决舰船管路系统的低频减振降噪问题,并对国内外声子晶体理论在管路系统的减振降噪应用探索进行了概述,最后给出将声子晶体引入舰船管路系统低频减振降噪仍需深入研究和探讨的几个方面问题.%The low-frequency sound and vibration control problems for ship piping systems are key and difficult ones to be solved in current ship design and manufacturing.Here,the causes for sound and vibration of ship piping systems were briefly analyzed.The bottleneck problems of current sound and vibration control techniques were presented after reviewing foreign and domestic noise and vibration reduction techniques for piping systems.Combining with the newly developed photonic crystals (PCs) technique for noise and vibration reduction in condensed matter physics area,PCs periodic structure design technique was proposed to solve the low-frequency sound and vibration control problems for ship piping systems.The explorations for applying the PCs theory in noise and vibration reduction of piping systems at home and abroad were reviewed.Finally,several problems to be needed further studying and exploring were presented for better sound and vibration control of ship piping systems via the PCs theory.
