Available in PDF, EPUB and Kindle. Book excerpt: Vibrations at a resonant frequency lead to catastrophic failure or at the very least, shorten the life span of the structure due to fatigue. These problems force engineers to implement damping techniques. Smart materials have been used over two decades to reduced vibration amplitudes. Recently, there has been much research and development on smart materials and structures. This work introduces an innovative approach for vibration suppression using passively shunted piezolectric materials. Initially linear circuit elements such as resistors, capacitors, and inductances, or building a non-linear circuit with different impedance designs were used. Instead of such elements, a switched electromechanical shunt has been proposed as a method to suppress vibrations of mechanical structures. In this state switching technique, bonded piezoelectric elements are switched from open circuit to closed circuit depending on the voltage produced from the piezoelectric patch. This new shunt circuit utilizes diodes. Diodes are nonlinear circuit elements and vibration amplitude is reduced due to introduction of nonlinearity into the system. A physics-based electro-mechanical model is developed and validated against experimental results. The smart plate consists of a rectangular aluminum plate modeled in cantilever configuration with surface bonded piezoelectric patches. Basic equations for piezoelectric sensors and actuators are presented. The equation of motion for the plate structure with bonded piezoelectric patch is depicted. The implementation of the circuit is demonstrated analytically and experimentally. The concept is demonstrated on two different modes and vibration peaks are lowered using the above mentioned circuit. Then a numerical model of the plate with the piezoelectric patch and the circuit is built in Simulink after designing a finite element model in ABAQUS. The data shows the effect of damping in Frequency Response Functions (FRFs) and in the response plots. A state-space model is also developed. Simulations of the model are compared to the experimental results. The results indicate the feasibility of the smart damping materials for many industrial applications where reducing noise and vibrations are desired. It is clear that the maximum suppression that can be obtained with this method is dependent on the voltage drop across the piezoelectric element.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook is an introduction to the dynamics of active structures and to the feedback control of lightly damped flexible structures; the emphasis is placed on basic issues and simple control strategies that work. Now in its fourth edition, more chapters have been added, and comments and feedback from readers have been taken into account, while at the same time the unique premise of bridging the gap between structure and control has remained. Many examples, covering a broad field of applications from bridges to satellites and telescopes, and problems bring the subject to life and take the audience from theory to practice. The book has 19 chapters dealing with some concepts in structural dynamics; electromagnetic and piezoelectric transducers; piezoelectric beam, plate and truss; passive damping with piezoelectric transducers; collocated versus non-collocated control; active damping with collocated systems; vibration isolation; state space approach; analysis and synthesis in the frequency domain; optimal control; controllability and observability; stability; applications; tendon control of cable structures; active control of deformable mirrors for Adaptive Optics and large earth-based and space telescopes; and semi-active control. The book concludes with an exhaustive bibliography and index. This book is intended for structural engineers who want to acquire some background in vibration control, and for control engineers who are dealing with flexible structures. It can be used as a textbook for a graduate course on vibration control or active structures. A solutions manual is available through the publisher to teachers using this book as a textbook.

Available in PDF, EPUB and Kindle. Book excerpt: The work of this thesis concerns to study of a particular technique related to the treatment of generated voltage by the piezoelectric elements. This nonlinear technique increases the effect of electromechanical conversion of piezoelectric materials considerably. This technique called Synchronized Switching Damping (SSD) has been developed in laboratory of electrical engineering and ferroelectricity of INSA-Lyon. The advantage of these techniques is that can be self-powered by using the converted electrical energy by piezoelectric elements. The presented work propose a new approach of control for the SSD techniques that allowing to increase of damping in the case of complex vibration such as random excitations. This new approach is the statistical approach on the sliding time window of the piezoelectric voltage or displacement of structure. Numerical as well as the experimental results have been presented for a cantilever beam. These results show the ability of the piezoelectric patches with passive shunting to damp out the structural vibration and also show that this new strategy of control is very efficient. The effect of the size of piezoelectric patches on the vibration damping and their damping sensibility to the variations of the excitation force parameters have been presented as well. Finally, it shows the effect of boundary conditions on the SSDI technique.

Book excerpt: Self sensing techniques allow using a piezoelectric transducer simultaneously as an actuator and as a sensor, as they reconstruct its mechanical sensory information by measuring its electrical quantities, i.e. voltage and charge. In vibration control applications piezoelectric self sensing actuators are highly desirable as they allow precise collocated control. Past research work was mainly based on the linear behavior of piezoelectric materials, thus restricting the operating driving voltages to low values. This work addresses the problem of using a self sensing piezoelectric actuator at its full driving voltage range. A new self sensing technique is proposed, which is based on the hysteretic modeling and identification of the piezoelectric transducer capacitance. After providing a sound presentation on piezoelectricity and vibrating structures, the most common self sensing techniques are discussed and the new self sensing technique is introduced and compared to typical linear methods both theoretically and experimentally.

Book excerpt: Vibration and structural acoustics analysis has become an essential requirement for high-quality structural and mechanical design in order to assure acoustic comfort and the integrity, reliability and fail-safe behavior of structures and machines. The underlying technologies of this field of multidisciplinary research are evolving very fast and their dissemination is usually scattered over different and complementary scientific and technical publication means. In order to make it easy for developers and technology end-users to follow the latest developments and news in the field, this book collects into a single volume selected, extended, updated and revised versions of papers presented at the Symposium on Vibration and Structural Acoustics Analysis, coordinated by J. Dias Rodrigues and C. M. A. Vasques, which was organised as part of the 3rd International Conference on Integrity, Reliability & Failure (IRF’2009), co-chaired by J. F. Silva Gomes and Shaker A. Meguid, held at the Faculty of Engineering of the University of Porto, Portugal, 20-24 July 2009. These papers where chosen from the more than 60 papers presented at the conference symposium. Written by experienced practitioners and researchers in the field, this book brings together recent developments in the field, spanning across a broad range of themes: vibration analysis, analytical and computational structural acoustics and vibration, material systems and technologies for noise and vibration control, vibration-based structural health monitoring/evaluation, machinery noise/vibration and diagnostics, experimental testing in vibration and structural acoustics, applications and case studies in structural acoustics and vibration. Each chapter presents and describes the state of the art, presents current research results and discusses the need for future developments in a particular aspect of vibration and structural acoustics analysis. The book is envisaged to be an appealing text for newcomers to the subject and a useful research study tool for advanced students and faculty members. Practitioners and researchers may also find this book a one-stop reference that addresses current and future challenges in this field. The variety of case studies is expected to stimulate a holistic view of sound and vibration and related fields and to appeal to a broad spectrum of engineers such as the ones in the mechanical, aeronautical, aerospace, civil and electrical communities.
