Investigation of performance in suppressing various vibrations with energy-recycling semi-active method

We conducted various investigations of energy-recycling semi-active vibration suppression by using piezoelectric transducers attached to structures. In this method, the converted electrical energy is recycled to suppress the vibration of structures instead of simply being dissipated. First, the energy-recycling semi-active method was applied to vibration suppression of a beam that is a typical continuous structure. Then, the method was applied to suppress the transient vibration of a membrane that is a typical tension-stabilized structure. Through these investigations, the energy-recycling method was found to be effective for use with various systems.
