摘　　要：高精度卫星上的光学探测系统的正常运行需要适当的低温环境,一般使用主动热控设备来满足这一要求,然而主动热控设备的运行会对安装面产生扰振力和扰振力矩,影响高精度卫星有效载荷所需要的微振动环境。本文以离心泵这类典型的卫星主动热控设备为研究对象,通过实验测得其振动特性,并在此基础之上设计了6自由度隔振系统,通过理论分析对隔振器的设计进行了优化,最后通过试验验证了隔振系统的振动抑制效果。The normal operation of optical detection system on high precision satellite needs suitable low temperature environment.Active thermal control equipment is generally used to meet this requirement.However,the active thermal control equipment will generate disturbance forces and torques on its installation surface,which will affect the operation quality of the satellite.In this paper,the pump,as a typical active thermal control equipment of the satellite,is taken as the research object.After measuring the vibration characteristics,the 6-DOF vibration isolation system is designed and optimized by theoretical analysis.Finally,the vibration suppression effect is tested by the experiment.
