In this paper, the main causes of spacecraft vibration are analyzed, and the influence of vibration on spacecraft can be reduced effectively by adopting reasonable vibration isolation measures. Taking the flywheel assembly of the spacecraft camera equipment under severe load as the research object, the vibration isolation model of the flywheel is analyzed, and the transfer function and the transmittance curve of the vibration isolation system are derived. The finite element simulation is carried out to obtain the modes of the camera equipment and the vibration value transmitted to the flywheel. The rubber vibration isolator suitable for installation in small space is designed, which can effectively isolate more than 70% of vibration.

摘要

In this paper, the main causes of spacecraft vibration are analyzed, and the influence of vibration on spacecraft can be reduced effectively by adopting reasonable vibration isolation measures. Taking the flywheel assembly of the spacecraft camera equipment under severe load as the research object, the vibration isolation model of the flywheel is analyzed, and the transfer function and the transmittance curve of the vibration isolation system are derived. The finite element simulation is carried out to obtain the modes of the camera equipment and the vibration value transmitted to the flywheel. The rubber vibration isolator suitable for installation in small space is designed, which can effectively isolate more than 70% of vibration.
