Active vibration control of a smart beam by using a spatial approach
Yaman, Yavuz; Şahin, Melin (I-Tech Education and Publishing, 2008-01-01)
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 beams and cylindrical structures using piezoelectric patches
Gençoğlu, Caner; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2014)
Airborne structures are required to be lightweight in today's designs. However this lowers the overall stiffness of the structure and causes low frequency vibration problems for which passive vibration control techniques are inadequate. Active vibration control using piezoelectric patches is a promising technology to solve vibration problems of aerospace structures. Many studies were done on beam and plate geometries, however studies on cylinder geometry which is used extensively as engineering structure, i...
Active vibration control of beam and plates by using piezoelectric patch actuators
Lüleci, İbrahim Furkan; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2013)
Conformal airborne antennas have several advantages compared to externally mounted antennas, and they will play an important role in future aircrafts. However, they are subjected to vibration induced deformations which degrade their electromagnetic performances. With the motivation of suppressing such vibrations, use of active vibration control techniques with piezoelectric actuators is investigated in this study. At first, it is aimed to control the first three bending modes of a cantilever beam. In this s...
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...
