车文根据对罗茨鼓风机噪声的实测结果,分析了噪声产生的机理,以必需的消声量频率特性为依据,设计了罗茨鼓风机排气消声器。实测结果表明,新设计的消声器性能良好,达到了预期目标。
According to the measured results of Roots blower noise, Che Wen analyzed the mechanism of noise generation, and designed Roots blower exhaust muffler based on the necessary frequency characteristics of noise attenuation. The measured results show that the newly designed muffler performance is good, has reached the expected goal.
