摘　　要：从振动力学的角度来看 ,斯特林制冷机的工作实际上是压缩活塞振子与排出器振子两个振动系统的耦合与匹配 ,两振动系统的相互影响特性对提高整机性能具有非常重要的意义。文中首先给出了压缩活塞振子与排出器振子两个振动系统相互影响特性的理论分析 。The interactional and matching relations of the compression piston and displacer vibration systems in a split-Stirling-cycle cryocooler are important for its operating performances. In this paper, theoretical analysis was given for the dual vibration systems; then their mutual influences were analyzed and discussed through comparison experimental results with the corresponding simulated ones.
