Experimental vibration analysis for civil engineering structures Dolnośląskie Wydawnictwo Edukacyjne

BUDOWNICTWO

Experimental vibration analysis is fast developing technology applied in civil engineering. Owners and users of the civil engineering structures require more safe, reliable and comfortable structures with low life cycle costs. The experimental vibration analysis offers valuable information and solutions for all above demands. Experimental vibration analysis is multidisciplinary area which can be defined as combination of civil engineering, electronic engineering and software engineering. The experts in this field should be familiar with the methods of data acquisition (sensors, excitation methods, metrology problems, etc.), data treatment (signal processing methods) and analysis (modal analysis, damage detection algorithms, etc.). Fast development of technologies used in experimental vibration analysis stimulates needs of international exchange of the knowledge and experience in the field of dynamic identification and assessment of civil engineering structures. Forum for the contacts is created by the International Conferences Experimental Vibration Analysis for Civil Engineering Structures EVACES. The first conference EVACES

Advanced Structural Dynamics and Active Control of Structures Springer-Verlag New York Inc.

Książki / Literatura obcojęzyczna

The book presents and integrates the methods of structural dynamics, identification and control into a common framework. It aims to create a common language between structural and control system engineers.Advanced Structural Dynamics and Active Control of Structures describes comparatively new areas of structural dynamics and control, and presents new tools to solve problems of dynamics and control. §It applies control system methods (such as state space representation, controllability and observability, grammians, system norms, and Markov parameters) to solve structural dynamics problems (e.g., sensor and actuator placement, identification, or damage detection), §It uses structural methods (such as modal analysis, and modal independence) to solve control problems (e.g., the design of LQG and H Yen controllers), and provides new insight into well-known control laws. §It is based on practical applications, originated from developing and applying techniques of structural dynamics, identification, and control to antennas and radiotelescopes. §It uses approximate approach in order to simplify analysis of large structural models (for example, to obtain Hankel singular values for a structure with thousands degrees of freedom), and to represent properties of large structures in closed form a form that is simple and easy to apprehend. §This book is a revision and continuation of Gawronski s previous book, Dynamics and Control of Structures. Three new chapters discuss special models, modal actuators and sensors, and system identification. Other chapters have been significantly revised and supplemented with new topics, including discrete-time models of structures, limited-time and frequency grammians and reduction, almost-balanced modal models, simultaneous placement of sensors and actuators, and structural damage detection. The updated and expanded appendices include programs that apply methods presented in the book in Matlab

Sandwich Structures: Theory and Responses Springer Nature Switzerland AG

Książki / Literatura obcojęzyczna

This book provides a solid foundation from which most practical, theoretical problems related to sandwich structures can be derived and solved. The text brings together many problems found in the literature, such as those concerning buckling, post-buckling, free vibration, and dynamic response under various types of loadings. Sandwich construction with functionally graded facings is also briefly discussed, wherein topics obtain theoretical solutions from one comprehensive, consistent theory. The basic governing equations are presented in orthogonal curvilinear coordinates considering the shallow shell theory, which includes the strain-displacement equations, the constitutive equations, equations of motion, and the compatibility equations. Providing a clear theoretical foundation for engineers and research scientists in need of detail on sandwich structures in professional practice, the book is an ideal reference for understanding these structures through a comprehensive treatment of the theory, mathematical procedures, and applications.

Lectures on Vibrations Akademia Marynarki Wojennej

MECHANIKA

Owing to their flexibility, the components of structures and machinery are capable of relative motion when subjected to internal or external forces. If such motion is oscillatory in nature, the motion is referred to as vibration. Although applications exist where vibration performs a useful function, vibration in ships is undesirable as it tends to accelerate the wearing of parts such as bearings and gears, create excessive noise and transmit significant forces and/or motion to accommodation, working and recreation spaces as well as to other equipment. Humans may be exposed to vibrations transmitted to the whole body or to particular parts of the body, such as the head or limbs. Designers should primarily be concerned with vibrations transmitted to the body through supporting surfaces such as the buttocks or feet. Research shows that mechanical vibration interferes with work quality and productivity, safety, health, comfort, and causes motion sickness. The literature also shows that vibration may modify crewmember perception (e.g., reading text and instruments, depth perception), influence task control movements (e.g., tactile sense, head/hand movements, manual tracking) and lead to impairment of speech. These factors may result in increased crewmember reaction/response times and possibility of human error. There are many different sources of vibration in ships, such as propeller and stern wake, main engine and other machinery, wave loads and environmental effects. Due to the complexity of these sources of excitation and of the structural configuration of ships, harmful vibration problems still occur even though vibration prediction techniques have developed rapidly and are well established through the use of Finite Element Method software. Continuing research activities have shown that carrying out vibration control is a tend as well as requirement for ships and offshore structures. Also in many other engineering branches it is well known that the proper vibration control in the design process is necessary a safe and satisfactory working and living environment as well as to avoid abnormal wear and tear on the machinery and structures. Since vibration and noise disturb the surrounding medium, their levels should be low also from reason, particularly in submarines. The appropriately reduced acoustic emission and electromagnetic signature of submarines decrease a vessel

Vibro-Acoustics, Volume 3 Springer-Verlag Berlin and Heidelberg GmbH & Co....

Książki / Literatura obcojęzyczna

This three-volume book gives a thorough and comprehensive presentation of vibration and acoustic theories. Different from traditional textbooks which typically deal with some aspects of either acoustic or vibration problems, it is unique of this book to combine those two correlated subjects together. Moreover, it provides fundamental analysis and mathematical descriptions for several crucial phenomena of Vibro-Acoustics which are quite useful in noise reduction, including how structures are excited, energy flows from an excitation point to a sound radiating surface, and finally how a structure radiates noise to a surrounding fluid. Many measurement results included in the text make the reading interesting and informative. Problems/questions are listed at the end of each chapter and the solutions are provided. This will help the readers to understand the topics of Vibro-Acoustics more deeply. The book should be of interest to anyone interested in sound and vibration, vehicle acoustics, ship acoustics and interior aircraft noise.

Principles of Mathematical Modeling Elsevier Science Publishing Co Inc

Książki / Literatura obcojęzyczna

Science and engineering students depend heavily on concepts of mathematical modeling. In an age where almost everything is done on a computer, author Clive Dym believes that students need to understand and 'own' the underlying mathematics that computers are doing on their behalf. His goal for "Principles of Mathematical Modeling, Second Edition", is to engage the student reader in developing a foundational understanding of the subject that will serve them well into their careers. The first half of the book begins with a clearly defined set of modeling principles, and then introduces a set of foundational tools including dimensional analysis, scaling techniques, and approximation and validation techniques. The second half demonstrates the latest applications for these tools to a broad variety of subjects, including exponential growth and decay in fields ranging from biology to economics, traffic flow, free and forced vibration of mechanical and other systems, and optimization problems in biology, structures, and social decision making.Prospective students should have already completed courses in elementary algebra, trigonometry, and first-year calculus and have some familiarity with differential equations and basic physics. The book: serves as an introductory text on the development and application of mathematical models; focuses on techniques of particular interest to engineers, scientists, and others who model continuous systems; offers more than 360 problems, providing ample opportunities for practice; covers a wide range of interdisciplinary topics - from engineering to economics to the sciences; uses straightforward language and explanations that make modeling easy to understand and apply. New to this edition: a more systematic approach to mathematical modeling, outlining ten specific principles; expanded and reorganized chapters that flow in an increasing level of complexity; several new problems and updated applications; expanded figure captions that provide more information; and, improved accessibility and flexibility for teaching.
