摘　　要：介绍利用传递矩阵法计算热声发动机的工作频率的思路和方法。理论分析表明该方法是切实可行的 ,和其他方法得到了相互的印证。利用该方法的计算结果和已发表的试验结果进行了对比分析。研究结果表明 ,相比已有的计算方法而言 ,传递矩阵法更加简单直观 ,方便于采用计算机编程计算复杂结构的热声系统的工作频率。Thermoacoustic engine, which can be used as heat driven compressor for cryocooler, is paid much attention because of its long life due to no moving parts. In order to improve the stability and the efficiency of the coupled thermoacoustic engine and coolers, the match of working frequency between them is very important. The working frequency of a thermoacoustic engine is nearest to the intrinsic frequency of the piping system. The approach of transfer matrix are introduced and described in this paper. The theoretical analysis, as well as the comparing between the calculation and the measured results, confirms that the approach of transfer matrix is convenient for the calculating the frequency of a thermoacoustic engine, especially for the complicated engines.
