Active Vibration Control of a Smart Beam
Yaman, Yavuz; Volkan, Nalbantoğlu; Eswar, Prasad; Davıd, Waechter (null; 2001-10-01)
This study presents an active vibration control technique applied to a smart beam. The smart beam consists of an aluminum beam modeled in cantilevered configuration with surface bonded piezoelectric (PZT) patches. The study uses ANSYS (v5.6) package program. The study first investigates the effects of element selection in finite element modeling. The effects of the piezoelectric patches on the resonance frequencies of the smart structure are also shown. The developed finite element model is reduced to a sta...
Active Vibration Suppression of a Smart Beam by Using a Fractional Order Control
Onat, Cem; Şahin, Melin; Yaman, Yavuz (2011-06-22)
In this study, a fractional order controller was designed and experimentally applied for the active vibration suppression of a smart beam. The smart beam was a cantilever aluminium beam equipped with eight symmetrically located surface-bonded PZT (Lead-Zirconate-Titanate) patches which were used both as sensor and actuator. For this particular application, a group of PZT patches closed to the root of the beam was used as actuators in the bimorph configuration and a single patch was nominated as a sensor. Fr...
Active vibration control of a smart beam : a spatial approach
Kırcalı, Ömer Faruk; Yaman, Yavuz; Department of Aerospace Engineering (2006)
This study presented the design and implementation of a spatial Hinf controller to suppress the free and forced vibrations of a cantilevered smart beam. The smart beam consists of a passive aluminum beam with surface bonded PZT (Lead-Zirconate-Titanate) patches. In this study, the PZT patches were used as the actuators and a laser displacement sensor was used as the sensor. In the first part of the study, the modeling of the smart beam by the assumed-modes method was conducted. The model correction techniqu...
Active Vibration Control of Smart Plates by Using Piezoelectric Actuators
Yaman, Yavuz; Volkan, Nalbantoğlu; Fatma Demet, Ülker; Eswar, Prasad; Davıd, Waechter; Bın, Yan (null; 2002-06-03)
Theoretical and experimental results of the modeling of a smart plate is presented for active vibration control. The smart plate consists of a rectangular aluminum plate modeled in cantilever configuration with surface bonded piezoelectric patches. The patches are symmetrically bonded on top and bottom surfaces. The study uses ANSYS (v.5.6) software to derive the finite element model of the smart plate. By using this model, the study first gives the influences of the actuator placement and size on the resp...
