Abstract
In order to study the influence of flywheel micro vibration on the imaging of a high resolution optical satellite, the flywheel components disturbance model was established, and the flywheel components were tested. The analysis of the measured data shows that there is a series of harmonic at the first order frequency 50Hz, and a series of peaks around the 190Hz and 280Hz. The integration of the angular displacement response that was obtained by exerting the unit sine excitation on the satellite and the flywheel measured disturbance data shows that there is a lot of angular displacement harmonic response frequency in 40Hz~80Hz and 230Hz~280Hz, the maximum angular displacement resonance response amplitude is 2.739" along the vertical direction, the angular displacement resonance response amplitude is 2.617" at 245Hz and 2600rpm, and 0.5" magnitude harmonic amplitude around 245Hz. Flywheel micro vibration has a great influence on the high resolution optical satellite imaging quality. Suggestions on further research on micro vibration of flywheel are proposed.
