星箭分离过程中，火工品解锁，卫星受到严酷的爆炸冲击环境，强烈的高频冲击环境可能使卫星上的电子、光学和其它敏感设备产生破坏。为减少卫星分离过程中相互之间产生的冲击作用，可在卫星与适配器之间安装减冲击环。本文对减冲击环的高频缓冲机理进行了研究，分析了冲击波的传递路径，在此基础上针对卫星模型进行了减冲击环设计，采用爆炸冲击模拟星箭分离冲击环境，对其缓冲效果进行了评估，拐点之后减冲击环能衰减10dB以上的冲击响应。
Abstract
During satellite-rocket separation, the satellites suppress serious pyroshock environment, which maybe damage the equipments on the satellite, such as electronic, optic or other sensitive equipments. To isolate the shock transmitted to satellite, shock ring can be fixed between satellite and adapter. In this paper, shock isolation mechanics of shock ring is studied in high frequency. The transmission path of shock waves is analyzed. On this basis, the shock ring for the satellite model is designed. The gunpowder is used to simulate satellite-rocket separation environment. The shock isolation property of shock ring is evaluated by pyroshock test. It shows that the shock response spectrum of satellite can be reduced 10dB by shock ring after inflection point.
