In recent years, passive vibration techniques were studied extensively due to their lightweight, cheapness, and simplicity, as compared with the active control techniques.In this research, we perform a vibration reduction task of a sandwiched composite panel, which may be used as a supporting platform for some scientific equipment in the space vehicle, by piezoelectric actuators with passive shunting circuits.To avoid the furious modes, which are hard to be controlled, due to the low in-plane stiffness of the honeycomb core, we have tried to adjust the sizes and fixtures of the panel.
