摘　　要：热声发动机压力特性主要体现在压力波形、相位、压比、压力振幅以及振荡频率等方面,是衡量热声发动机性能的重要依据之一。实验研究了加热温度、充气压力、谐振管长度、工质种类、负载等对压比、压力振幅、频率等压力特性的影响,为更好地进行热声发动机的设计和应用奠定了基础。The pressure characteristic in a thermoacoustic prime mover mainly displays in the pressure wave, pressure phase, pressure ratio, pressure amplitude and resonance frequency. It’s one of the important characteristics that show the performance of the thermoacoustic prime mover.The pressure characteristic in thermoacoustic prime mover is studied and the effect of heating temperature, filling pressure, resonant tube length, working gas and load on the pressure characteristic are analyzed. It will be helpful to the further design and application of the thermoacoustic prime mover.
