Aiming at the strict requirement of pointing stability and dynamic environment of optical spacecrafts with micro vibrations in reaction flying wheels or other attitude actuators, this paper presents a passive double-layer micro-vibration control concept. The proposed micro-vibration system comprises of two Stewart isolators. The first Stewart isolator is designed to suppress the micro vibrations of reaction flying wheels. To further improve the pointing stability, this paper designs another Stewart isolator to suppress the micro vibrations of spacecraft body. The proposed double-layer micro-vibration control system of a flexible optical spacecraft is analyzed using Patran/Nastran software. The simulation results demonstrate that the micro-vibration control system presents enhanced dynamic environment and pointing stability.
