“…During photographing of the in-orbit satellite, micro-vibrations, caused by motion of the moving parts, such as reaction wheels, solar array drive motors, and cryo-coolers, can seriously degrade the image quality. Despite the fact that it is not responsible for damage to the structure of the satellite, mico-vibration will affect the pointing accuracy and stability of high resolution satellite (Lee et al 2015). Reaction wheels are commonly used to control the attitude of a satellite and consist of a rotating flywheel suspended on ball bearings encased in a housing and driven by an internal brushless DC motor (Bialke, 1998).…”

“…Reaction wheels are commonly used to control the attitude of a satellite and consist of a rotating flywheel suspended on ball bearings encased in a housing and driven by an internal brushless DC motor (Bialke, 1998). Owing to the rotor imbalance, static imbalance, driving motor error, bearing defects and other factors, the reaction wheel assemblies (RWAs) will generate harmonic disturbance, which makes the reaction wheel become one of the key sources of micro-vibrations (Lee et al, 2015).…”

“…The isolation performance in microgravity environment can achieve 10-30 dB attenuation of acceleration on the band of 0.1-300 Hz. 26 Lee et al 27,28 investigated a hybrid isolator of bellows and viscous fluid; the experimental results showed that the passive isolator can achieve a high roll-off rate of about À40 dB/dec, and the amplification at the resonance frequency is about 6.5 dB.…”

“…[2] realizou comparações entre dois modelos de absorvedores de energia para baixa frequência, através do modelo de Zener. Outro trabalho utilizando o modelo de Zeneré o de [3], que realizou analise experimental de isoladores de vibração desenvolvidos para aplicação espacial emórbita capaz de isolar micro-vibrações, e também suportar ambiente de lançamento onde há vibração severa.…”
