摘要

波纹消声器可实现特定频带上的消声最大化，通过调节不同波纹深度的重新组合获取非规则波纹结构来实现频带上的互补。采用侧支共振腔理论公式计算单波纹传递损失，依据双负载原理搭建实验台测量波纹管声学性能，将理论、实验结果分别与数值预测值进行比较。研究结果表明：波纹深度是影响单波纹共振频率的主要因素；非规则波纹结构传递损失带宽主要受非规则波纹数量、相邻波纹深度差影响；消声腔容积影响有效带宽频率范围。最终优化结果相比常规波纹管，在1000-5000Hz内传递损失均值提升约20.55dB，带宽拓宽约1750Hz。

Abstract

The corrugated muffler can maximize the muffling in specific frequency bands, and the frequency bands are complemented by adjusting the recombination of different corrugation depths to obtain irregular corrugated structures. Calculate the transmission loss of single bellows by using the theoretical formula of side-branch resonance cavity, and measure the acoustic performance of bellows by constructing an experimental bench based on the double-loading principle, compare theoretical and experimental results with numerical predictions. The results showed that the corrugation depth is the main factor affecting the resonance frequency of single corrugated structures; Irregular corrugated structure transfer loss bandwidth is mainly affected by the number of irregular corrugations, the depth difference of adjacent corrugations; The volume of the anechoic chamber affects the effective bandwidth frequency range. The final optimized result improves the mean value of transmission loss by about 20.55 dB in 1000-5000 Hz and broadens the bandwidth by about 1750 Hz compared to the conventional bellows.
