Research of Whole-satellite Vibration Isolation Based on Shear Damper |

| Abstract: | The satellite experienced complex vibration shock environment during the launch vehicle was in flight. Severe dynamic environment caused bad effects on the life of satellite, made the satellite losing efficacy and even destroyed the satellite completely. In this paper, energy absorption vibration damping principle of viscoelastic damping material was researched and design program of whole-satellite vibration damping structure was proposed. Numerical simulation prediction and test of combination structure of simulated satellite, adapter and whole-satellite vibration damping devices was carried out and the result showed that the simulation results were consistent to the test data which validated the effectiveness of whole-satellite vibration damping technology based on shear damping. |
