本文对铜丝网叠层热声原动机进行了测量。共振频率低于100 Hz，这意味着该动子可用于驱动脉冲管制冷机。研究了起始温度和共振频率。结果发现，在某些条件下，二次谐波分量成为主导和原动机基本上工作在第二模式，这应该避免。测量了气体性质、频率、平均压力、网格尺寸和堆叠长度对整体性能的影响，并以归一化输入功率、加热器温度和压力幅值表示。在频率为73Hz、输入功率为833W、加热器温度为700K的条件下，热声原动机的最大输出功率为26W。
Measurements of thermoacoustic prime movers with stacks made of copper wire mesh are presented. The resonance frequencies were below 100Hz, which means the movers can be used to drive pulse-tube refrigerators. Onset temperature and resonance frequency were studied. It was found that, under certain conditions, the second harmonic component becomes dominant and the prime mover essentially works on the second mode, which should be avoided. The influence of gas properties, frequency, mean pressure, mesh size and stack length on the overall performance are measured and expressed in terms of normalized input power, heater temperature and pressure amplitude. A maximum output power of 26W from the thermoacoustic prime mover was achieved with the frequency, input power and heater temperature 73Hz, 833W and 700K, respectively.
