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 meydana getirmektedirler. Bu özellikler piezoelektrik malzemelerin algılayıcı ve uyarıcı olarak kullanılmasını sağlamaktadır. Çalışmamızda öncelikle, piezoelektrik yamalar algılayıcı ve uyarıcı olarak kullanılarak sistemin frekans cevabı elde edilmişve analitik sistem modeli bulunmuştur. Daha sonra, bu sistem modeli kullanılarak gürbüz kontrolcü tasarımı yapılmıştır. Son olarak, akıllı kirişin serbest ve ilk rezonans frekansındaki zorlanmıştitreşim sonuçları açık ve kapalı döngüler olarak verilmiştir.

Piezoelektrik yamaların akıllı bir kirişin titreşim özelliklerinin bulunmasında algılayıcı olarak kullanılması Arıdoğan, Uğur; Şahin, Melin; Nalbantoğlu, Volkan; Yaman, Yavuz (null; 2009-06-22) 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 perfo...
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...
Piezoelectric ceramics and their applications in smart aerospace structures Çalışkan, Tarkan; Yaman, Yavuz; Nalbantoğlu, Volkan; Department of Aeronautical Engineering (2002) This thesis investigates some applications of smart structures in aerospace engineering. The smart structures considered are finite and flat aluminum beam-like and plate-like structures with surface bonded PZT (Lead-Zirconate-Titanate) patches. The smart structures are studied in cantilevered configuration. The thesis gives the theoretical and experimental studies conducted on the smart structures with particular attention given to the vibration control aspects. In the determination of the structural models...
Numerical calculation of homogenized properties of piezoelectric composites Kurt, Mustafa; Gürses, Ercan; Department of Aerospace Engineering (2022-11-25) Piezoelectric materials are the materials we use in many parts of our lives without being aware. These materials can convert electrical energy into mechanical energy or vice versa. Although this ability renders piezoelectric ceramics very attractive materials for sensing and actuation applications, their use often remains limited, due to their weight and brittleness. As a result of these drawbacks, piezoelectric composites are developed, and they offer superior performance compared to monolithic piezoelectr...
Design and Optimization of Nanoantennas for Nano-Optical Applications Işıklar, Göktuğ; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2020-9) In this study, design and simulation of plasmonic nanoantenna structures to obtain high power enhancement capabilities at optical frequencies, as well as utilization of nanoantennas for imaging and sensing applications are presented. Plasmonic characteristics of nanoantennas, which depend on many parameters, such as material, frequency, geometry, and size, are investigated in detail via computational analyses of various nanoantenna structures. Numerical solutions of electromagnetic problems are performe...
