线性压缩机目前是长寿命斯特林制冷机和高温斯特林制冷机常用的压缩机。本文首先分析了阻尼系数在压缩机运行过程中对压缩机的影响, 然后对线性压缩机阻尼系数测试方法进行了理论分析, 最后对昆明物理研究所线性压缩机的阻尼系数进行了测试分析。通过理论分析给出了线性压缩机的阻尼计算方法, 并搭建真空实验平台测试出压缩机的阻尼系数。对昆明物理研究所 SCI09H制冷机的线性压缩机和 SCI15H制冷机的线性压缩机进行了阻尼测试, 测试结果表明不同线性压缩机的阻尼系数并不完全相同。

Linear compressors are commonly used in both long-life and high-temperature Stirling coolers. Using linear compressors from the Kunming Institute of Physics, this study analyzed the effects of different damping coefficients of these linear compressors by employing a damping calculation method derived from theoretical analysis. The damping coefficients of linear compressors were tested using a vacuum testing platform. Test results showed that the damping coefficients of different linear compressors were not identical.
