摘　　要：振动试验作为分置式制冷机环境试验的重要部分,如何准确的在不同频率下对制冷机进行试验检测,成为判断其性能稳定性的重要环节之一。常见的电动振动台无法实现低频(1 Hz)起振,往往需要专用振动台才能满足低频实验条件。本文通过对通用型振动台起振失败的问题进行试验分析,对振动系统进行优化,从而使其满足分置式制冷机低频振动试验要求。Vibration test,as an important part of environmental test for split stirling cryocooler,how to accurately test and detect the cryocooler at different frequencies becomes one of the important links to judge its performance stability.Common electric vibration table can not achieve low frequency(1 Hz)vibration,often require specialized vibration tables to meet the low frequency experimental condition.In this paper,the vibration system was optimized to meet the low frequency vibration test requirements of the split stirling cryocooler by testing and analyzing the failure of the general vibration table.
