摘　　要：针对某型汽车研发过程中存在的进气系统噪声问题,利用赫姆霍兹谐振腔的消声原理对谐振腔的结构进行了优化和改进。试验结果表明改进后的谐振腔消声效果很好。To solve the noise problem of a vehicle＇s intake system in the development process, the structure of the resonator was optimized and improved by using the muffling principle of Helmholtz resonator. The experimental results showed that the improved resonator had good noise muffling effect.
