  1. 704 Active Vibration Control of a Flexible Rotating Arm Based on the Wave Absorbing Control Principle , NISHIGAKI Tsutomu , Dynamics and Design Conference : D & D , 2015 , "704 , 1"-"704-6" , 25, Aug. 2015
    Summary:In this study, a wave absorbing technique, i.e. the technique which cancels the reflection wave at the end point of the flexible thin structure, was investigated using piezoelectric films. A smart cantilever beam, on which appropriately shaped piezoelectric film sensors and actuators were bonded, was manufactured. Theoretical analysis and experiments were performed and it was shown that vibration control effects will be expected for broad band frequency range including several vibrational modes. Furthermore, vibration control effects in the laboratory experiment showed good agreement with those in the theoretical analysis when the excitation frequencies were low enough. It was also confirmed that it is difficult to apply the proposed method with piezoelectric devices to the flexible rotation arms, since the influence of the inertial force cannot be neglected in the experiments. Finally, a perspective toward the design method of smart structural cantilever beams, which contain optimized sensors, actuators, main structures and controllers, was discussed.
  2. A203 Active sound insulation control of a thin plate using piezoelectric films , NISHIGAKI Tsutomu , Dynamics and Design Conference , 2015 , 14 , 203 , 206 , 22, Jun. 2015
    Summary:Active sound insulation control effect of a flexible thin plate using piezoelectric film, especially for the cases in which the plate were much more thinner than that reported in the conventional studies, was investigated theoretically and experimentally. At first, fundamental equations were summarized for a rectangular thin plate with rectangular-shaped piezoelectric film sensor and actuator. Then, vibration response of the plate and sensor output response of the piezoelectric film was derived based on the modal expansion method. Output frequency response of the system was estimated by the volume velocity, which was one of the suitable indexes when sound insulation effects were discussed. Finally, active sound insulation experiment of an acrylic plate of thickness around 0.3mm with a bonded PVDF film actuator was performed to verify the fundamental characteristics and performances of the proposed controlled structures.

    Summary:In this study, a wave absorbing technique, i.e. the technique which cancels the reflection wave at the end point of the flexible thin structure, was investigated using piezoelectric films. At first, a cantilever beam, which can be applied to the flexible rotating arm, was introduced as the controlled structural model. Then, a smart cantilever beam, on which appropriately shaped piezoelectric film sensors and actuators were bonded, was manufactured. Theoretical analysis and experiments were performed and it was shown that vibration control effects will be expected for broad band frequency range including several vibrational modes. Furthermore, vibration control effects in the laboratory experiment showed good agreement with those in the theoretical analysis when the excitation frequencies were low enough. It was also confirmed that it is difficult to apply the proposed method with piezoelectric devices to the flexible rotation arms, since the influence of the inertial force cannot be neglected in the experiments.
