摘要 报道了一种高频驻波热声发动机驱动脉冲管制冷机的热声不稳定现象。通过实验对此种热声不稳定现象的产生原因进行了探讨,发现增加加热功率或缩短声压放大器可以抑制此种不稳定现象;理论方面主要通过快速傅立叶变换对不稳定的压力波形进行分析,对其产生原因进行了初步分析。 An unstable phenomenon happened in a high frequency thermoacoustically driven pulse tube cooler is introduced. Different experiments are used to find the cause of this phenomenon. Two methods, which include increasing heating power and deducing the length of the acoustic pressure amplifier, are proposed to suppress this unstable phenomenon. FFT is used to analyze the abnormal oscillation process, and preliminary explanation is presented.
