Switching shunt damping technique is one of the most effective methods for structural vibration control due to its simplicity and robustness. However, because of the spillover, conventional switching LR shunt damping technique has limitation of its application to multi degree-of-freedom systems. In this paper, we propose a new switching shunt damping technique to reduce vibration of a specified mode of multi degree-of-freedom systems. Basic idea of the proposed method is to recover the loss of electrical charge of the piezoelectric element by charge supply from parallel connected capacitors. Effectiveness of the proposed method is examined numerically and experimentally.
