Abstract
The vibration isolator is the major solution to suppress the disturbance caused by high-frequency vibration of the satellite, but it is difficult to resolve the conflicts between the attenuation in the resonance region and the high-frequency attenuation in design. This paper studies the vibration attenuation of attitude control actuators. Control moment gyroscopes, chosen as the attitude control actuators, are installed on a vibration attenuation platform consisted of a vibration isolator and vibration absorbers. The motion of equations of the whole satellite including the vibration attenuation platform is established. Then, the dynamic characteristics of the vibration isolator are analyzed, and the optimization of vibration absorbers is conducted. Finally, a system of parameters design method of the vibration attenuation platform is proposed, which satisfies the requirement of vibration attenuation and guarantees the stability of the attitude control system.
