摘　　要：近年来,气体驱动斯特林制冷机在比重量、可靠性、振动和噪声等方面得到提高,在红外技术和超导电子学等领域具有诱人的应用前景,其研究工作一直是低温领域的一个热点。首先简要描述了气动型斯特林制冷机气动腔内气体热力迟滞行为特性,其次主要理论推导该部分气体热力迟滞行为特性造成的损失,并且给出了一个计算机仿真结果说明该项损失对制冷机性能的影响。本文对更为逼真地仿真微型气动斯特林制冷机的热动力特性行为提供了有力支撑。Pneumaticallydriven Stirling cryocoolers have the advantages of low mass,low vibration and noise,and high reliability in recent years,so they have luring applications in the infrared technology,superconductive electronics,and etc.The thermodynamic hysteresis effect of spring gas in the pneumaticallydriven Stirling cryocooler has been presented and mainly made a detailed theoretical analysis.In the meantime,a loss equation has been derived and a simulation result was provided for verifying the influence of this thermodynamic hysteresis effect.These results will be the important support for the dynamic simulation about the miniature pneumaticallydriven Stirling cryocoolers.
