| 摘 要： | 针对某车用空气滤清器分别设计了导流管、1/4波长管和穿孔板结构,并以减声量为评价指标对各种措施的应用效果进行了分析.结果表明,在原空气滤清器上增加3种消声措施后,在保持原空气滤清器宽频带较高消声效果的同时,有效提高了频率在295 Hz、620 Hz和750 Hz下的减声量;改进后空气滤清器的整体减声量为87 dB,比原型提高14dB,对空气滤清器的结构改进达到了较为满意的效果.

| Abstract: | The inflow conduit,1/4 wave pipe and perforated plate structure are designed separately for an automotive air cleaner,and the effect of different designs in noise reduction is analyzed.The results show that,with three noise reduction measures applied to the original air cleaner,the noise reduction effect is improved effectively at the frequency of 295 Hz,620 Hz and 750 Hz while maintaining the high noise reduction at wide frequency band of the original air cleaner;a total of 87 dB noise is eliminated with t... |
