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 control of a smart sandwich plate Aksoy, Yunus Tansu; Şahin, Melin (null; 2016-09-08) In aerospace engineering, sandwich construction is preferred not only for its great decrease in weight but also for its advantage of smooth surfaces and perfect fatigue resistance. However, lots of vibration problems occur in these light weight structures. In this study, the first three vibration modes of a smart sandwich plate are aimed to be suppressed by using active vibration control techniques comprising a pole placement controller. Smart sandwich plate is composed of a passive sandwich composite plate...
Active vibration control of a smart sandwich plate via piezoelectric sensors and actuators Aksoy, Yunus Tansu; Şahin, Melin; Department of Aerospace Engineering (2015) In this study, the first three vibration modes of a smart sandwich plate, which are 1st out-of-plane bending, 1st torsion and 2nd out-of-plane bending modes, are aimed to be suppressed by using active vibration control techniques comprising a pole placement controller. Smart sandwich plate is composed of a passive sandwich composite plate and piezoelectric patches (PZT Lead-Zirconate-Titanate) attached with epoxy adhesive at specific locations determined by using finite element modelling and analysis. Those...
Active vibration control of smart structures Ülker, Demet Fatma; Yaman, Yavuz; Nalbantoğlu, Volkan; Department of Aerospace Engineering (2003) The purpose of this thesis was to design controllers by using H^ and yn control strategies in order to suppress the free and forced vibrations of smart structures. The smart structures analyzed in this study were the smart beam and the smart fin. They were aluminum passive structures with surface bonded PZT (Lead-Zirconate-Titanate) patches. The structures were considered in clamped-free configuration. The first part of this study focused on the identification of nominal system models of the smart structure...
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...
