Abstract

As an effective means of separating the vibration transmitted from rocket to satellite, the Whole-Spacecraft Vibration Isolation (WSVI) has been widely studied and applied in the past 20 years. Based on a new Circular Payload Adapter Fitting (CPAF), this paper studied the vibration principles of the CPAF and established corresponding vibration isolation model. With the piezoelectric stack actuators, integrated passive and active vibration control was achieved based on passive vibration control. Model simulation results show that the CPAF has good vibration isolation performance, and could reduce the vibration transmitted from rocket to satellite in a wide frequency band.
