提高柴油机排气消声器消声性能的试验研究

Text Research on Improving Ac oustic Performance of Diesel Engine Exhaust Silencer

针对柴油机排气消声器 ,将流体计算软件用于阻力特性分析 ,并采用对试验件进行静态放声试验的方法 ,优化消声器的声学设计以提高消声效果。

In the paper, the FLUENT software is used to an alyze the pressure loss in a diesel engine exhaust silencer, and the method of m aking static acoustic test is applied to optimize the acoustic structure design of the silencer so as to improve its noise reducing performance.
