摘　　要：为了在不同位置获得不同的制冷性能,设计了一台线性对置压缩机驱动两台同轴型脉管冷指的实验方案并搭建了试验台。通过实验研究两台脉管制冷机耦合的制冷性能。实验结果显示:两台设计相同的脉管冷指性能不同,经过耦合后制冷性能差异更大,可同时达到1.79 W@60 K和1.384 W@60 K制冷量。In order to achieve refrigeration at different positions, two coaxial pulse tube cryocoolers op- erated by single linear opposed compressor were designed to investigate. The test bench was conducted. The performances of two matching pulse tube cryocoolers were investigated by the test bench. Experimental re- sults show that the characters of two pulse tube cryocoolers designed identically were different. After cou- pling, the differences on the performances between the two pulse tube cryocoolers were more obvious. The two pulse tube cryoeoolers could achieve cooling capacities of 1.79 W at 60 K and 1. 384 W at 60 K simultaneously.
