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.
