In this study, vibration characteristics of a smart beam are investigated by using piezoelectric patches as sensors. Smart beam is excited by either impact hammer or piezoelectric patch and the frequency response of the system to these excitations are obtained from a piezoelectric patch used as sensor. The effect of the location of the piezoelectric sensor on frequency response of the system is also presented by choosing different piezoelectric patches along the smart beam. In order to investigate the performance of the piezoelectric patch in sensing, all results are then compared to those obtained from theory, single-axis accelerometer and laser displacement sensor.

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...
Akilli Bir Kirişin Titreşimlerinin Doğrusal Karesel Düzenleyici (LQR) ile Aktif Denetimi
Akın, Onur; Şahin, Melin (Theoretical and Applied Mechanical Turkish National Committee; 2015-08-24)
In this study, active vibration control of a smart beam equipped with piezoelectric patches which are used as both sensor and actuator is investigated by using linear quadratic regulator (LQR) method. Frequency response function that includes the first natural frequency of the smart beam is obtained by applying exponential sine wave within the specified frequency range to the piezoelectric actuator patch and measuring the response of the system from another piezoelectric patch as a sensor. Then, by using th...
Piezoelektrik Yamaların Akıllı Bir Kirişin Titreşim Kontrolünde Algılayıcı ve Uyarıcı Olarak Kullanılması
Arıdoğan, Uğur; Şahin, Melin; Nalbantoğlu, Volkan; Yaman, Yavuz (2009-07-02)
Bu bildiride, akıllı bir kirişin titreşim kontrolünde piezoelektrik (PZT) yamaların algılayıcı ve uyarıcı olarak kullanılması sunulmuştur. Akıllı kiriş olarak tanımlanmış yapı, piezoelektrik yamaların tek ucu tutturulmuş ve diğer ucu serbest olan alüminyum kirişin her iki yüzeyine simetrik olarak yapıştırılmasıyla oluşturulmuştur. Piezoelektrik malzemeler, boyutsal şekil değişikliklerine zorlandıklarında elektrik sinyali ürettikleri gibi elektriksel alana maruz bırakıldıklarında da boyutsal değişiklik meyda...
Nonlinear modeling of piezoelectric stack actuators with flexure based displacement amplifier mechanisms
Yurdakul, Ozan; Özer, Mehmet Bülent; Yıldız, Erdinç Nuri; Department of Mechanical Engineering (2022-8-26)
In this thesis, modeling methods for piezoelectric stack actuators (PSA) are studied. Both linear and nonlinear modeling methodologies are provided. FEM which is derived from constitutive piezoelectric equations is implemented to model linear behavior of piezoelectricity. Validation of the FEM model is performed through experiments. It is observed that modeling and test results are matched with high quality. Rhombus type amplifier mechanism (RTAM) is selected for this study after conducting a detailed liter...
Silver nanowire networks on polydimethylsiloxane for organic and perovskite solar cell electrodes
Güner, Elif Özlem; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2019)
Transparent and conductive electrodes are widely used in optoelectronic devices. The most prominent and commercial transparent conductive electrode is indium tin oxide (ITO). However, there is an increasing demand to replace ITO with alternative materials due to inherent drawbacks of ITO such as its cost, brittleness and scarcity of indium. Silver nanowire (Ag NW) networks are among the best candidates to replace ITO with their excellent optoelectronic and mechanical properties. Ag NW networks have already ...
