共振消声器吸收压力脉动的动态分析及仿真计算

The Dynamic Analysis and Simulation of Minifying Pressure Pulsation by Reed Bore Muffler

研究了一种共振消声器———亥姆霍兹共振消声器。首先建立了共振消声器的数学模型,从频率特性角度讨论了共振消声器对压力脉动的削减作用,最后使用MATLAB进行了仿真计算,得到了三种脉动频率下压力脉动的削减幅度,其计算结果与仿真结果基本吻合。

The mathematic model of reed bore muffler was set up, and the minifying pressure pulsation was studied based on frequency. The model was simulated by MATLAB, the minifying extent of pressure pulsation under three pulsation frequency were obtained, which accords with the calculation result.
