研制了一种用于高温超导装置的斯特林制冷机。在开发过程中强调高效率和长寿命。在23°C环境条件下，输入150 W，70 K时性能为6 W;在50°C环境条件下，70 K时产生5 W，消耗150 W。该设计的平均失效前时间超过40，000小时。弯曲弹簧用于支撑冷头中的压缩机气缸和置换器，以实现此寿命。使用有限元建模（FEM）设计柔性弹簧，以将应力降低到疲劳极限以下。
A Stirling cryocooler for high temperature superconducting devices has been developed. High efficiency and long lifetime are emphasized in the development. Its performance is 6 W at 70 K with 150 W input under 23°C ambient conditions; at 50°C ambient, it produces 5 W at 70 K with 150 W consumption. The mean time before failure for the design is over 40,000 hours. Flexure springs are used to support the compressor cylinders and the displacer in the cold head to realize this lifetime. The flexure springs are designed using finite element modeling (FEM) to reduce the stress to below the fatigue limit.
