This research focuses on a finite element analysis of active vibration suppression capabilities of a smart composite platform, which is a structural interface between a satellite main thruster and its structure and possesses simultaneous precision positioning and vibration suppression capabilities for thrust vector control of a satellite. First, the combined system of the smart composite platform and the satellite structure are briefly described followed by the finite element modeling and simulations. The smart platform piezoelectric patches and stacks material properties modeling, for the finite element analysis, are developed consistent with the manufacturer data. Next, a vibration suppression scheme, based on the modal analysis, is presented and used in vibration suppression analysis of satellite structures of the thrust vector under the thruster-firing excitation. The approach introduced here is an effective technique for the design of smart structures with complex geometry to study their MIMO active vibration suppression capabilities.
