排气消声器的结构参数与其消声效果的关系——基于台架试验的分析

Test Measurement and Performance Evaluation Analysis of Exhaust Muffler

通过台架试验,分析评价几种结构参数不同的排气消声器的空气动力性能。按照相关测量标准配置噪声测量分析系统,测量消声器的传递损失;依据试验所得的出口风速,分析评价结构参数不同的消声器的空气动力性能。试验结果表明,结构参数优化后的消声器,其空气动力性能和消声效果都相对更好。

In this paper, the noise measurement and analysis system is configured according to the relevant measurement standard through the exhaust muffler bench test. By the test which measured the transmission loss of muftier, the aerodynamic pefformance of the muffler is indirectly evaluated according to the rate of outlet wind speed. Finally, the feasibility and correctness of the theoretical muffler design and optimization computation are verified.
