Nowadays, the engineering practice raises far more vibration problems than can be theoretically explained or modelled. Because Df this, measurements are used in almost all fields of industry, transportation and civil engineering in studies of mechanical and structural vibration. They are an invaluable tool for designing products and machines with high reliability and low noise level, vehicles and buildings with improved comfort and resistance to dynamic loads, as well as for obtaining increased safety of opera tion and optimum running parameters. In order to cope with the increasing demand for experimental measurement of vibration characteristics, young engineers and designers need an introductory book with emphasis on "what has to be measured" and "by what means" before learning "how measurements are done". The expertise to perform vibration measurements must be gained in time, with every new investi gation and studied problem . .A detailed presentation of instrumentation and measuring techniques is beyond the aim of this book. Such information can be found in product data sheets, application manuals and hand books supplied by equipment manufacturers. Only general princi ples and widely used methods are presented herein, in order to provide the reader with an overview of the instrumentation and techniques encountered in vibration measurement.

Controlling a system's vibrational behavior, whether for reducing harmful vibrations or for enhancing useful types, is critical to ensure safe and economical operation as well as longer structural and equipment lifetimes. A related issue is the effect of vibration on humans and their environment. Achieving control of vibration requires thorough und

Noise and Vibration Analysis is a complete and practical guide that combines both signal processing and modal analysis theory with their practical application in noise and vibration analysis. It provides an invaluable, integrated guide for practicing engineers as well as a suitable introduction for students new to the topic of noise and vibration. Taking a practical learning approach, Brandt includes exercises that allow the content to be developed in an academic course framework or as supplementary material for private and further study. Addresses the theory and application of signal analysis procedures as they are applied in modern instruments and software for noise and vibration analysis Features numerous line diagrams and illustrations Accompanied by a web site at www.wiley.com/go/brandt with numerous MATLAB tools and examples. Noise and Vibration Analysis provides an excellent resource for researchers and engineers from automotive, aerospace, mechanical, or electronics industries who work with experimental or analytical vibration analysis and/or acoustics. It will also appeal to graduate students enrolled in vibration analysis, experimental structural dynamics, or applied signal analysis courses.

This technical book deals with the design and function of vibration measurement systems, how they are put into operation and how measurements are interpreted. It describes the functioning of the entire measurement chain from the transducer to the evaluation, and explains the interaction of the elements as well as the practically used procedures of signal processing and evaluation and clarifies them with numerous practical examples.

Noise and Vibration affects all kinds of engineering structures, and is fast becoming an integral part of engineering courses at universities and colleges around the world. In this second edition, Michael Norton's classic text has been extensively updated to take into account recent developments in the field. Much of the new material has been provided by Denis Karczub, who joins Michael as second author for this edition. This book treats both noise and vibration in a single volume, with particular emphasis on wave-mode duality and interactions between sound waves and solid structures. There are numerous case studies, test cases, and examples for students to work through. The book is primarily intended as a textbook for senior level undergraduate and graduate courses, but is also a valuable reference for researchers and professionals looking to gain an overview of the field.

Machinery Vibration Analysis and Predictive Maintenance provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined. The acquisition and processing of signals is then reviewed followed by a discussion of machinery fault diagnosis using vibration analysis. Hereafter the important issue of rectifying faults that have been identified using vibration analysis is covered. The book also covers the other techniques of predictive maintenance such as oil and particle analysis, ultrasound and infrared thermography. The latest approaches and equipment used together with the latest techniques in vibration analysis emerging from current research are also highlighted. - Understand the basics of vibration measurement - Apply vibration analysis for different machinery faults - Diagnose machinery-related problems with vibration analysis techniques

Vibration Measurement and Analysis presents the different approaches of vibration measurement and analysis techniques. The book begins with a discussion of the reasons for conducting vibration measurements. Subsequent chapters cover topics on general measurement requirements, transducers and the measurement of sound, and signal conditioning and recording. Analysis methods and frequency analysis, techniques of correlation and averaging, and automation of vibration testing are discussed as well. Mechanical engineers will find the book very useful.

An aid to those who make and interpret blast vibra­tion measurements, this book serves as an especially useful and timely introduction Wave phenomena are a familiar part of everyone’s experi­ence. Water waves are perhaps the most graphic, but the existence of sound waves, light waves, and electromagnetic radio and television waves is also well known. The destruc­tive effect of earthquake waves receives widespread publicity. It is thus obvious that gases, liquids, and solids will support wave motion. For the understanding and analysis of blast vibrations, scientists and engineers require a sophisticated understanding of wave phenomena. G. A. Bollinger in Blast Vibration Analysis makes an important contribution to this study focusing on the origin, transmission, and types of elastic wave in solid media. The physical laws involved in waves analysis as well as the mathematical tools needed to specify and analyze the variety of wave phenomena en­countered in nature are also provided. Mr. Bollinger synthesizes the theory and literature from the seismological, geophysical, and engineering disciplines pertinent to the subject area of blast vibrations induced by quarrying, mining, and engineering operations. While the theory and analytical techniques presented do apply to vibra­tions from earthquakes and nuclear explosions, the author avoids developing a specific consideration of those latter phenomena. However, he applies the analytical tools that have been so highly refined in earthquake engineering, earthquake seismology, and seismic exploration for petro­leum, i.e., digital and spectral analyses, to the blast vibration problem. Dividing his book into five textual chapters, Mr. Bollinger devotes the first two to a detailed consideration of seismic waves, both from a general physical viewpoint as well as from the effects of blasting. The third chapter covers the mathematical theory of the seismograph along with examples of instruments currently used by professionals. A very specific discussion of the analysis of blast vibrations, including steady-state, suddenly-beginning, digital, and trace-match­ing analyses is presented in the fourth chapter. The con­cluding chapter considers damage criteria, both American and European, along with the structural and physiological effects of blast vibrations. Mr. Bollinger’s skillful exposition of each of these topics starts at an elementary level—assum­ing some college engineering or scientific background—proceeds to an intermediate stage, and then suggests direc­tions for more advanced study. While the theoretical presen­tation is kept general, specific examples and certain relevant points are made with reference to Sprengnether seismic instruments. Each chapter is followed by a list of references, and a bibliography of the field of engineering seismology as a whole appears at the back of the book. Numerous informative tables, figures, graphs, charts, mathematical examples, and photographs of instruments are included in the body of the text. Scientific students and professionals will find Mr. Bol­linger’s book stimulating and suggestive of further ranges of study and practice.
