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.

Following the routine of a normal day, from coffee and breakfast to shopping, household chores, sports, a drink, supper, and a bath, we see how the seemingly mundane can provide insight into the most profound scientific questions. Some of the topics included are the art and science of dunking; how to boil an egg; how to tally a supermarket bill; the science behind hand tools; catching a ball or throwing a boomerang; the secrets of haute cuisine, bath (or beer) foam; and the physics of sex. Fisher writes with great authority and a light touch, giving us an entertaining and accessible look at the science behind our daily activities.
Two physically different dampers (magnetorheological and controlled-friction) are analysed from the perspectives of mechatronics and control. Ride comfort, road holding, road damage and human-body modelling (nonlinear visceral response in particular) are studied.
A multidisciplinary approach is adopted throughout the book. Sound mathematical modelling is balanced by a large and detailed section on experimental implementation, where a variety of automotive applications are described offering a well-rounded view of the application of such systems. The implementation of control algorithms with regard to real-life engineering constraints is emphasised.
The applications described include semi-active suspensions for a saloon car, seat suspensions for vehicles not equipped with a primary suspension, and control of heavy-vehicle dynamic-tyre loads to reduce road damage and improve handling.
Engineers and practitioners working in noise and vibration; automotive engineers working in vehicle design, research and development; biomechanical engineers, physicists and life-scientists interested in human-body responses to vibration; and graduate students in vehicle studies, mechanics of vibration, dynamics and control will find this book of material assistance in their work.

In the ever-evolving field of protective relay technology, an engineer’s personal preference and professional judgment are as important to power system protection as the physical relays used to detect and isolate abnormal conditions.
Invaluable Insights from an Experienced Expert
Protective Relay Principles focuses on probable power system failure modes and the important characteristics of the protective relays used to detect these postulated failures. The book presents useful new concepts in a way that is easier to understand because they are equally relevant to older, electromechanical and solid-state relays, and newer, more versatile microprocessor-based relays. It introduces the applications, considerations, and setting philosophies used in transmission-line, distribution-line, and substation applications, covering concepts associated with general system operations and fault detection. Topics include relay load limits, cold load pickup, voltage recovery, and arc flash. The author also delves into the philosophies that engineers employ in both urban and rural areas, with a detailed consideration of setpoint function.
Analysis of Key Concepts That Are Usually Just Glossed Over
This versatile text is ideal for new engineers to use as a tutorial before they open the instruction manuals that accompany multi-function microprocessor-based relays. Guiding readers through the transient loading conditions that can result in relay misoperation, the author elaborates on concepts that are not generally discussed, but can be very helpful in specific applications. Readers will come away with an excellent grasp of important design considerations for working with overcurrent, over- and undervoltage, impedance, distance, and differential type relay functions, either individually or in combination. Also useful for students as a textbook, this book includes practical examples for many applications, and offers guidance for more unusual ones.

Beginning with current training needs, Mechanical Design reinforces the fundamentals of the design of mechanical components. It employs an analytical approach to the subjects based on algorithms from traditional calculus without extensive reference to more current methodologies. This gives students of the ability to use simple models and calculations that are reliably effective and helpful at times when more complicated algorithms or well-known commercial programs need to be used.
Emphasizing logical and analytical thinking, students start by analyzing the physical problem with the most appropriate schematic and end with a constructional definition of the component in need of planning. Typical Machine Construction course subjects/modules occupy the greater part of this book (mechanical system component planning), but two preliminary sections enhance its appeal: the methodological set-up of the project (traditional or more recent developments), and the project criteria that take into account environmental concerns. To comply with the requirements of the new teaching regulations, the principal materials tests and simple stress states are outlined prior to the study of fatigue, which refers to fine-tuning methods developed at Catania’s Faculty of Engineering. Two useful appendices group tables of the general properties of metallic materials, and there are various applications whose theoretical methods and tools are applied to the planning of real mechanical systems.

Working systematically from general principles to specific applications, coverage spans from theory and experimental techniques in vibration damping to isolation, passive control, active control, and structural dynamic modification. The book also discusses specific issues in designing for and controlling vibrations and noise such as regenerative chatter in machine tools, fluid-induced vibration, hearing and psychological effects, instrumentation for monitoring, and statistical energy analysis. This carefully edited work strikes a balance between practical considerations, design issues, and experimental techniques.
Complemented by design examples and case studies, Vibration Damping, Control, and Design builds a deep understanding of the concepts and demonstrates how to apply these principles to real systems.
Doctors Savaresi and Tanelli show how these different control approaches are complementary, each having specific peculiarities in terms of either performance or of the structural properties of the closed-loop system. They also consider other problems closely related to the design of braking control systems, namely:
• longitudinal vehicle speed estimation and its relationship with braking control system design;
• tire–road friction estimation;
• direct estimation of tire–road contact forces via in-tire sensors, with the aim of providing a comprehensive treatment of active vehicle braking control from a wider perspective linked to both advanced academic research and industrial reality.
