In the authors' previous report, a smart and simplified self-sensing actuator technique using piezoelectric films with different thickness and area was proposed, in which two rectangular shaped piezoelectric films are bonded on one surface of the structure and treated as two capacitors in the active RC bridge circuit. The validity of the proposed method was shown by performing vibration control experiments of a cantilever beam and a circular ring. In this report, the present method is applied to multimodal vibration control of simply supported beam as fundamental flexible structure. At first, fundamental equations of the system based on the proposed method are derived using energy principle and vibration control effects are estimated by numerical analysis to show effective shapes of the two films for multi-mode vibration control of simply supported beam.
