摘　　要：斯特林制冷机微振动是影响光学遥感成像品质的重要振动源,压缩机振动影响尤为严重。介绍了某型制冷机压缩机微振动产生原理、抑制方程和控制办法,并通过实验验证将斯特林制冷机压缩机微振动降低40%。该控制方法现已在各类制冷机中应用,效果良好。The vibration of Stifling cryocoolers is an important vibration source that affects the quality of optical remote sens- ing imaging. The vibration of the compressor is particularly serious. The mechanism of vibration generation, suppression equation and control method of a eryocooler compressor were introduced, and reduction of vibration of the compressor was experimentally verified. The control method can be applied in various types of cryocoolers with good effects.
