摘　　要：在自然进化的过程中,许多鸟类翅膀不断进化,其翅膀结构能够达到几乎静音飞行的效果,以此为参考,仿鸟类翅膀结构的降噪技术发展迅速。仿生降噪是减少声污染的一种有效手段,在航空、航天和机械制造等诸多行业应用广泛。为深入研究仿鸟类翅膀结构的降噪技术及其应用,全面了解国内外研究现状,本文以结构布置位置为划分依据,详细介绍了三种常见的降噪结构,并对其降噪效果进行详细分析。仿生降噪是突破结构设计瓶颈的有效方法,也是积极响应国家减少声污染,降低噪声号召的有利体现。Bionic noise reduction is an effective means to reduce acoustic pollution,which is widely used in many industries such as aviation,aerospace and machinery manufacturing.In the process of natural evolution,many birds'wings evolve continuously,and their structures can achieve the effect of almost silent flight.Taking this as a reference,the noise reduction technology imitating the structure of birds'wings has developed rapidly.In order to deeply study the noise reduction technology and its application of bird like wing structure,comprehensively understand the research status at home and abroad,introduce and analyze the noise reduction effect of the structure in detail from three common structural layout positions,which is an effective method to break through the bottleneck of structural design,and also a favorable embodiment of actively responding to the national call to reduce noise pollution and reduce noise.
