摘要
将排气噪声分为三类,研究了间歇性排气过程中的空气动力学和噪声特性,建立了间歇性排气噪声中的单极子源和四极子源所产生噪声的声压级表达式。对气路系统中各参数对噪声的影响进行了全面深入的研究。
Exhaust noise is divided into three classes. Aerodynamics characteristics and the noise characteristics inthe course of illtermittence exhaust are investigated.The expressions for sound pressure level of the noise generated byannuploe source and quadrupole source induced by the intermittence exhaust noise are established. Effects of each of allparameters in pneumatic system on the noise value are comprehensively and thoroughly studied.
