Piezoelectric Transducers for Vibration Control and Damping (Advances in Industrial Control)
By S.O. Reza Moheimani, Andrew J. Fleming,
Publisher: Springer
Number Of Pages: 271
Publication Date: 2006-06-02


Flexible mechanical systems experience undesirable vibration in response to environmental and operational forces. The very existence of vibrations can limit the accuracy of sensitive instruments or cause significant errors in applications where high-precision positioning is essential so in many situations control of vibrations is a necessity. Piezoelectric transducers have been used in countless applications as sensors, actuators, or both. When traditional passive vibration control techniques fail to meet requirements, piezoelectric transducers in conjunction with feedback controllers can be used effectively to suppress vibrations. Piezoelectric Transducers for Vibration Control and Damping presents recent developments in vibration control systems that employ embedded piezoelectric sensors and actuators. In particular, it covers various ways in which active vibration control systems can be designed for piezoelectric laminated structures, paying distinct attention to how such control systems can be implemented in real time. The text contains numerous examples and experimental results obtained from laboratory-scale apparatus, with details of how similar setups can be built. Features and topics: An overview of piezoelectricity. Modelling of flexible structures with embedded piezoelectric sensors and actuators. Feedback control of structural vibration using PPF and resonant controllers. A comprehensive treatment of piezoelectric shunt damping systems using systems-theoretic tools. A paradigm for designing active high-performance piezoelectric shunts. Innovative techniques to deal with the problem of hysteresis in piezoelectric transducers. Instrumentation for piezoelectric sensors and actuators. Applications in atomic force and scanning tunneling microscopy. An essential text and reference for graduates, researchers, and professionals working in mechanical engineering, aerospace engineering and mechatronics disciplines, this book will be a specially useful resource for scientists and engineers engaged in vibration control research

Publisher: CRC
Number Of Pages: 976
Publication Date: 1999-12-16
ISBN / ASIN: 0849318084

Vibration: Fundamentals and Practice provides the background and techniques that allow successful design, analysis, and modification of vibration in mechanical systems. It focuses on the practical aspects of vibration-the applications and design considerations directly related to modifying vibrational behavior in mechanical devices and structures. The author presents a uniform and coherent treatment of the subject, integrating material on instrumentation, experimentation, design, and control and offering numerous case studies and worked examples. Introduces practical applications and experimental techniques in the very beginning, then uniformly integrates them throughout the book o Provides mathematics and dynamics background in appendices Includes many worked examples and case studies o Describes the industry-standard and state-of-the-art software tools for analysis and design of vibratory systems and illustrates them with examples o Offers analogies to other oscillatory systems, such as electrical and fluid systems, and contrasts these with thermal systems

Structural Vibration, Analysis and Damping
By C. Beards
* Publisher: Butterworth-Heinemann
* Number Of Pages: 276
* Publication Date: 1996-05-31
* ISBN / ASIN: 0340645806

Book Description:

Many structures suffer from unwanted vibrations and, although careful analysis at the design stage can minimise these, the vibration levels of many structures are excessive. In this book the entire range of methods of control, both by damping and by excitation, is described in a single volume.

Clear and concise descriptions are given of the techniques for mathematically modelling real structures so that the equations which describe the motion of such structures can be derived. This approach leads to a comprehensive discussion of the analysis of typical models of vibrating structures excited by a range of periodic and random inputs. Careful consideration is also given to the sources of excitation, both internal and external, and the effects of isolation and transmissability. A major part of the book is devoted to damping of structures and many sources of damping are considered, as are the ways of changing damping using both active and passive methods. The numerous worked examples liberally distributed throughout the text, amplify and clarify the theoretical analysis presented. Particular attention is paid to the meaning and interpretation of results, further enhancing the scope and applications of analysis. Over 80 problems are included with answers and worked solutions to most. This book provides engineering students, designers and professional engineers with a detailed insight into the principles involved in the analysis and damping of structural vibration while presenting a sound theoretical basis for further study

Vibration Simulation Using MATLAB and ANSYS
By Michael R. Hatch

* Publisher: Chapman & Hall/CRC
* Number Of Pages: 654
* Publication Date: 2000-09-21
* ISBN / ASIN: 1584882050
Book Description
Incorporating the use of MATLAB to help with the solution of problems, this text explores the subject of vibration from a fairly sophisticated, mathematical point of view. With a three degree-of-freedom (DOF) system as a unifying theme, the author develops the associated equations of motion, then in each chapter includes both a closed-form solution and the MATLAB code for solving a problem. The book's unique approach makes it especially useful for engineers who lack experience with state space, and it will prove useful to both the mechanical and control engineering communities in enhancing their ability to communicate

Inverse Problems in Vibration: Second Edition (Solid Mechanics and Its Applications)
By Graham M.L. Gladwell
* Publisher: Springer
* Number Of Pages: 457
* Publication Date: 2004-08-30
* ISBN / ASIN: 1402026706

About this book
In the first, 1986, edition of this book, inverse problems in vibration were interpreted strictly: problems concerning the reconstruction of a unique, undamped vibrating system, of a specified type, from specified vibratory behaviour, particularly specified natural frequencies and/or natural mode shapes.

In this new edition the scope of the book has been widened to include topics such as isospectral systems- families of systems which all exhibit some specified behaviour; applications of the concept of Toda flow; new, non-classical approaches to inverse Sturm-Liouville problems; qualitative properties of the modes of some finite element models; damage identification.

With its emphasis on analysis, on qualitative results, rather than on computation, the book will appeal to researchers in vibration theory, matrix analysis, differential and integral equations, matrix analysis, non-destructive testing, modal analysis, vibration isolation, etc.
