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 response of the smart plate and determines the maximum admissible piezoelectric actuation voltage. Based on this model, the optimal sensor locations are found and actual smart plate is produced. The experimental results of that smart plate are then used in the determination of a single input single output system model. By using this model, a single-input/single-output H∞ controller is designed to suppress the vibrations due to the first two flexural modes of the smart plate. It has been shown that the designed controller guaranties robust performance.

Nonlinear Transverse Vibrations of a Beam with Multiple Breathing Edge Cracks
Batihan, Ali C.; Ciğeroğlu, Ender (2017-02-02)
One step beyond the studies of transverse vibration of beams with a breathing edge crack is the verification of the theoretical crack beam models with an experimental test set up. Beams with a single breathing edge crack can be used as a specimen for the experimental test. However, there is no assurance against the unexpected additional cracks in the specimens, whichmay cause unexpected results. Therefore, in this paper nonlinear transverse vibration of a beam with multiple breathing edge cracks is consider...
Performance evaluation of piezoelectric sensor/actuator on investigation of vibration characteristics and active vibration control of a smart beam
Arıdoğan, Mustafa Uğur; Şahin, Melin; Department of Aerospace Engineering (2010)
In this thesis, the performance of piezoelectric patches on investigation of vibration characteristics and active vibration control of a smart beam is presented. The smart beam is composed of eight surface-bonded piezoelectric patches symmetrically located on each side of a cantilever aluminium beam. At first, vibration characteristics of the smart beam is investigated by employment of piezoelectric patches as sensors and actuators. Smart beam is excited by either impact hammer or piezoelectric patch and th...
Active vibration suppression of a smart beam via self sensing piezoelectric actuator
Uğur, Arıdoğan; Şahin, Melin; Yaman, Yavuz; Volkan, Nalbantoğlu (null; 2009-08-17)
In this paper, an active vibration suppression of a smart beam using self-sensing piezoelectric actuator is presented. The smart beam is composed of a cantilever aluminium beam with four surface-bonded piezoelectric patches symmetrically located both side of the beam. Piezoelectric materials can transform mechanical deformation to electric signal and vice versa. This property of piezoelectric materials enables them to be used as an actuator and a sensor. In self-sensing actuator configuration, the piezoelec...

We present the design, characterization, theoretical and experimental verification of a tunable perfect metamaterial absorber (MA) based electromagnetic (EM) energy harvesting and sensor application. We have used the golden ratio while determining the dimensions allowing a simple configuration and an easy fabrication for the proposed structure. We have examined and analyzed the perfect absorption (both numerically and experimentally) and EM energy harvesting (numerically) behaviors of the proposed structure...
