Many sensing instruments sent into Earth orbit require cooling to extremely low temperatures. However, reliability and vibration considerations have until recently precluded the use of active refrigeration systems for spacecraft sensors. The problems of reliability and residual vibrations have been overcome, leading to the development of a practical active refrigerator, called a cryocooler, for spacecraft applications. This paper describes the development of a nonlinear, coupled fluid-structural dynamics code which has been used for the basic mechanical design of the moving mechanisms within cryocoolers.
