EXPLORATORY DEVELOPMENT OF GAS SPRINGS AS APPLIED TO ROTARY-RECIPROCATING CRYOGENIC COOLERS.
Abstract
The purpose of this program was the exploratory development of gas springs as applied to rotary-reciprocating cryogenic cooling equipment. A gas spring mathematical model was developed and used to design an experimental test apparatus. The test apparatus was fabricated and subjected to testing which demonstrated the design concept and execution to be workable and practical. Power losses were larger than anticipated and indicate that a more sophisticated analytical model is necessary for accurate sizing of gas spring systems. Losses due to irreversible heat transfer in the gas spring chamber appear to be the most significant cause of power loss. Further testing is necessary to evaluate performance over a wider range of frequencies and stroke amplitudes and to determine what effect chamber geometry has on these irreversible losses. (Author)
