摘要	In order to avoid image quality degradation of optical remote sensing satellite induced by flywheel micro-vibration, a combined vibration isolation device is designed, and the rationality of the vibration isolation scheme is verified by combining simulation with experiment. Firstly, the measured flywheel perturbation data is introduced into the finite element model to calculate the pixel offset of the optical camera caused by the flywheel vibration. Secondly, the combined vibration isolation scheme is designed and the isolation effectiveness is verified based on the finite element analysis. Finally, the micro-vibration measurement experimental platform is constructed to measure the pixel offset caused by the micro-vibration of the flywheel at different speeds. The experimental results demonstrate that the combined vibration isolation device significantly suppresses the high-frequency vibration of the flywheel above 300 Hz, the maximum pixel offset is reduced to 0.01 pixel, and the vibration reduction efficiency is over 80%. The experimental results show high consistency with the simulation in the response of fundamental harmonic and whirl mode at low frequency band. However, the test and simulation results have some differences in the response of high frequency band. 2020, Editorial Dept. of JA. All right reserved.
