中文摘要: |
本文分析了周期间隙性排气噪声的声学特性,提出对该噪声滤波消声器的要求,试验研究了不同滤波单元的滤波特性,在此基础上建立了降低该类噪声滤波消声器总成结构,并对其进行了台架及工厂实际使用验证,证明该滤波消声器具有较高的实际应用与推广价值。 |
英文摘要: |
In this paper, the acoustic characteristics of period-interval exhaust noise are analysed and requirements for muffler filtering the noise are suggested. Filtering characteristics of different filtering unit are also studied by test. On the basis of above study, a complete structure of muffler for noise reduction is established. The muffler is actually tested in a test-bed and in factory reality. Test results show that such muffler possesses a high value of practical application |
