高性能直线压缩机的出现，以其振动小、寿命长、结构紧凑等优点，促进了斯特林式制冷机的迅速发展。目前，对线性压缩机使用的研究大多集中在冷头的高效率和输出声功率（pV功率）上。然而，除了上述两个参数外，冷头的高性能运行还需要足够的输入压力幅值，这可以定义为所需功率的质量。本文利用复向量法对线性压缩机的输出压力幅值进行了图形化研究。与谐波振荡分析相比，活塞应力和速度的复矢量图可以更容易地理解压缩机压力幅值输出特性的分析。基于矢量图推导出线性压缩机输出最大压力幅值和最大pV功率下压力幅值的估算公式，可用于线性压缩机的设计和选型。实验验证了理论分析的正确性。计算比较了不同运行参数和结构参数对线性压缩机输出压力幅值的影响。结果表明，频率和活塞面积是提高输出压力幅值的最优参数，这也有利于压缩机的紧凑性。
The advent of high-performance linear compressor has promoted the rapid development of Stirling type cryocoolers due to its advantages of low vibration, long life and compactness. At present, most of the studies on the usage of the linear compressor are focus on the high efficiency and output acoustic power (pV power) for the cold head. However, besides the above two parameters, the high-performance operation of the cold head also requires enough input pressure amplitude, which can be defined as the quality of the required power. In this study, the output pressure amplitudes of the linear compressor were graphically investigated with the help of the complex vector method. Compared to harmonic oscillation analysis, the complex vector diagram of the piston stress and velocity can provide an easier understanding for analyzing the pressure amplitude output characteristics of the compressor. Equations for estimating the output maximum pressure amplitude and the pressure amplitude under the maximum pV power of a linear compressor were deduced based on the vector diagram, which can be used for the design and selection of linear compressors. Experiments were done to verify the theoretical analysis. Influences of different operating and structure parameters on the output pressure amplitudes of the linear compressor were calculated and compared. It shows that the frequency and piston area are the optimal parameters for improving the output pressure amplitudes, which also benefits the compactness of the compressor.
