摘　　要：动磁式线性压缩机目前是长寿命斯特林制冷机比较常用的线性压缩机。以昆明物理研究所的LFC3600动磁式线性压缩机为研究对象,对压缩机的磁路进行了理论分析,数值计算和实验研究。理论分析给出了动磁式线性压缩机的磁阻和磁动势计算式。数值计算分析了动磁线性压缩机的磁感应强度和磁力线分布。实验研究采用了一种新的磁感应强度测试方法,测试结果和数值分析结果能够得到很好地吻合。Moving magnet linear compressors are very popular compressor in tactical miniature stirling cryocoolers. This paper studied LFC3600 moving magnet linear compressor manufactured by Kunming institute of physics. The analysis theory, numerical calculation and experiment research are used in the analysis. The calculated formula of magnetic reluctance and magnetomotive force are given in theoretical analysis model. The magnetic flux density and magnetic： flux line are analyzed in numerical analysis model. A novel testing method is designed to test magnetic flux density of linear compressor, and results are almost equal to numerical results.
