摘　　要：分置式斯特林制冷机广泛应用于空间红外遥感探测器中,由于制冷机存在运动部件,工作过程中不可避免的产生振动输出,是影响探测器正常工作的主要振动源之一。为保证探测器正常工作,制冷机微振动必须足够小。从分置式斯特林制冷机微振动控制和隔振设计方面进行了研究,分析了制冷机微振动影响的主要因素,并对整机隔振理论进行了分析,将理论与实践相结合,从而有效降低制冷机的微振动,满足探测器的使用要求。The split Stirling cryocooler is widely used in space infrared remote sensing detectors. Because of the inevitable vibration output of the moving parts in operation of the split Stirling cryocooler, it is one of the main vibration sources that affect the regular operation of the detector. In order to ensure the regular operation of the detector, the micro vibration of the split Stirling cryocooler must be small enough. In the paper, the micro vibration control and vibration isolation design for the split Stirling cryocooler were carried out. The main factors to affect the micro vibration were analyzed. The theory and practice were combined to effectively reduce the micro vibration of the split Stirling cryocooler and satisfy the requirements of the detector.
