| 摘 要： | 在数值解耦分析的基础上,对复杂穿孔管消声器中几种常见的穿孔管结构进行分析,推导出了各自的传递矩阵。与声学有限元分析结果进行比较,结果表明数值解耦分析结果与有限元分析结果在中低频率范围内具有较高的精度。数值解耦分析方法对复杂穿孔管消声器的研究具有一定的指导意义;并且相对于有限元分析节约了大量的时间。

| Abstract: | In this paper, several common structures of perforated tube in the complex muffler are analysed based on the numerical decoupling analysis, and deducing the respective transfer matrix. Compared with the acoustic finite element analysis results, the results show that the numerical decoupling analysis and acoustic finite element analysis have high precision in the low and medium frequency range. Therefore, the numerical decoupling analysis method has certain guiding significance to the study of perforated tube muffler, and saves much time compared with the acoustic finite element analysis method. |
