摘　　要：振动水平是低温制冷机的重要性能指标之一,而振动问题往往是低温制冷机应用于冷却敏感仪器的最主要瓶颈。系统介绍了低温制冷机的振动测量方法和振动形成机理的研究进展,并对目前低温制冷机的主要减振措施进行了整理与归纳。还对目前低温制冷机减振措施中存在的问题和发展趋势做了探究。Vibration is one of the important performance parameters of cryocoolers. The vibration problem has become a main obstruction during cryocooler＇s application in the cooling of vibration - sensitive instrumentation. This article gives an summary of the vibration measurement and the vibration mechanism of cryocoolers. Main vibration - reduction methods are introduced in details. The R＆D tendencies of vibration - reduction is also discussed.
