摘要
声学黑洞结构作为一种轻质、高效、宽频弹性波调控手段,在减振降噪领域具备广阔的应用前景。本文基于声学黑洞效应,以轻质高效宽频减振降噪材料用于解决工程声振问题为目的,介绍了单层/双层声学黑洞梁和附加声学黑洞吸振梁、声学黑洞压痕板和内雕板、声学黑洞圆柱壳,以及声学黑洞管道减振降噪的研究进展。结合当前声学黑洞减振降噪研究和应用过程中存在的不足,对声学黑洞减振降噪领域存在的问题和未来的研究方向进行预判,为声学黑洞减振降噪研究和应用提供一些参考。
Acoustic black hole structure,as a lightweight,efficient and wide-band elastic wave control method,has a broad application prospect in the field of vibration and noise reduction.Based on the acoustic black hole effect,the purpose of this paper is to use lightweight and high efficient broadband vibration and noise reduction materials to solve the engineering sound and vibration problems.This paper introduces the research progress of single-layer and double-layer acoustic black hole beam and additional acoustic black hole vibration absorption beam,acoustic black hole indentation plate and inner engraved plate,acoustic black hole cylindrical shell and acoustic black hole pipeline.Combined with the shortcomings in the current research and application of acoustic black hole vibration and noise reduction,the problems existing in the field of acoustic black hole vibration and noise reduction and the future research direction are predicted,which provides some reference for the research and application of acoustic black hole vibration and noise reduction.
