Vibration Fundamentals

All mechanical equipment in motion generates a vibration profile, or signature, that reflects its operating condition. This is true regardless of speed or whether the mode of operation is rotation, reciprocation, or linear motion. There are several predictive maintenance techniques used to monitor and analyze critical machines, equipment, and systems in a typical plant. These include vibration analysis, ultrasonics, thermography, tribology, process monitoring, visual inspection, and other nondestructive analysis techniques. Of these techniques, vibration analysis is the dominant predictive maintenance technique used with maintenance management programs, and this book explains the basic theory, applications, and benefits in one easy-to-absorb volume that plant staff will find invaluable

Gear Noise and Vibration

Illustrated with over 150 figures, this text for researchers and development engineers (and interested graduate students) describes various practical and economical approaches to dealing with gear noise and vibration. The focus is on basic non-mathematical ideas of how vibrationis generated by the transmission error and how it progresses through the system. The second edition offers new coverage of high- and low- contact ratio gears. Smith teaches engineering at Cambridge University

Engineering Vibration Analysis with Application to Control Systems

Most machines and structures are required to operate with low levels of vibration as smooth running leads to reduced stresses and fatigue and little noise. This book provides a thorough explanation of the principles and methods used to analyse the vibrations of engineering systems, combined with a description of how these techniques and results can be applied to the study of control system dynamics. Numerous worked examples are included, as well as problems with worked solutions, and particular attention is paid to the mathematical modelling of dynamics systems and the derivation of the equations of motion

Practical Balancing Rotating Machinery

Rotating machinery (eg pumps, motors, compressors) is normally manufactured to precise measurements but there comes a point when the costs of manufacture mean that further precision is not cost-effective and thus any slight imbalance inherent in the machine will need to be attended to after manufacture. When such machinery is in operation, often at very high speeds of thousands of revs per minute, any imbalance will set up vibration and often noise. In addition, such imbalance will cause extra wear and loss of efficiency in the machine. The answer is to balance the affected parts of the machine so that it operates smoothly and efficiently.

Vibration Fundamentals and Practice

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

Piezoelectric Transducers for Vibration Control and Damping

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 piezoelectricsensors 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
