Abstract
Vibration generated by small Stirling-cycle cryocoolers is an important concern for spacecraft designers planning to incorporate these cryocoolers into near-term space-science instruments. Under joint Air Force/Ballistic Missile Defense Organization (BMDO) and NASA Eos/AIRS Instrument sponsorship, JPL has an extensive ongoing cryocooler characterization program addressed to measuring the important cryocooler performance characteristics such as self-generated vibration; these measurements provide the interface and trend data needed by instrument designers as well as valuable feedback for improving cryocooler performance.
Self-generated vibration has been measured at JPL for a wide variety of Stirling cryocoolers, from early engineering development model coolers to flight coolers. These data, when viewed as a whole, provide insight into a variety of generic cryocooler vibration trends. Data are presented which characterize the sensitivity of cryocooler vibration to operational parameters such as stroke and drive frequency, to different harmonic cancellation approaches, and to the influence of the stiffness of the cooler structural mount. The data are presented for all three translational axes as well as for the moment about the drive axis.
