Book Description
Slow speed rotating machines are the mainstay of several industrialapplications worldwide. They can be found in paper and steel mills, rotating biological contractors, wind turbines etc. Operational experience ofsuch machinery has not only revealed the early design problems but has alsopresented opportunities for further significant improvements in the technologyand economics of the machines. Slow speed rotating machinery maintenance, mostly related to bearings, shafts and gearbox problems, represents the causeof extended outages. Rotating machinery components such as gearboxes, shafts and bearings degrade slowly with operating time. Such a slowdegradation process can be identified if a robust on-line monitoring andpredictive maintenance technology is used to detect impending problems andallow repairs to be scheduled. To keep machines functioning at optimal levels, failure detection of such vital components is important as any mechanicaldegradation or wear, if is not impeded in time, will often progress to moreserious damage affecting the operational performance of the machine. Thisrequires far more costly repairs than simply replacing a part. Over the last few years there have been many developments in the use ofAcoustic Emission (AE) technology and its analysis for monitoring the conditionof rotating machinery whilst in operation, particularly on slow speed rotatingmachinery. Unlike conventional technologies such as thermography, oilanalysis, strain measurements and vibration, AE has been introduced due to itsincreased sensitivity in detecting the earliest stages of loss of mechanicalintegrity. This programme of research involves laboratory tests for monitoring slow speedrotating machinery components (shafts and bearings) using AE technology. Toimplement this objective, two test rigs have been designed to assess thecapability of AE as an effective tool for detection of incipient defects within lowspeed machine components (e.g. shafts and bearings). The focus of theexperimental work will be on the initiation and growth of natural defects. Further, this research work investigates the source characterizations of AE signalsassociated with such bearings whilst in operation. It is also hoped that at theend of this research program, a reliable on-line monitoring scheme used forslow speed rotating machinery components can be developed.

Book Description
This book is intended for those using, wishing to use, or wishing to understand, the use of Acoustic Emissions/Ultrasonics applied to the condition monitoring of industrial machinery. This technique provides a relatively easy way to improve monitoring of traditionally awkward items such as plain bearings, slow speed machinery, worm/wheel gears and machines of either unknown design or for which there have been no previous measurements. This is a practical book, touching on the basic theory and concepts, available equipment and practical issues relevant to the engineer as well as highlighting several case studies with which the reader can relate. The book is laid out in such a way that its chapters and sections follow a logical order for those wishing to read from cover to cover, but more importantly it can be used for quick reference purposes on a topic by topic basis.

Book Description
"Without doubt the best modern and up-to-date text on the topic, wirtten by one of the world leading experts in the field. Should be on the desk of any practitioner or researcher involved in the field of Machine Condition Monitoring" Simon Braun, Israel Institute of Technology Explaining complex ideas in an easy to understand way, Vibration-based Condition Monitoring provides a comprehensive survey of the application of vibration analysis to the condition monitoring of machines. Reflecting the natural progression of these systems by presenting the fundamental material and then moving onto detection, diagnosis and prognosis, Randall presents classic and state-of-the-art research results that cover vibration signals from rotating and reciprocating machines; basic signal processing techniques; fault detection; diagnostic techniques, and prognostics. Developed out of notes for a course in machine condition monitoring given by Robert Bond Randall over ten years at the University of New South Wales, Vibration-based Condition Monitoring: Industrial, Aerospace and Automotive Applications is essential reading for graduate and postgraduate students/ researchers in machine condition monitoring and diagnostics as well as condition monitoring practitioners and machine manufacturers who want to include a machine monitoring service with their product. Includes a number of exercises for each chapter, many based on Matlab, to illustrate basic points as well as to facilitate the use of the book as a textbook for courses in the topic. Accompanied by a website www.wiley.com/go/randall housing exercises along with data sets and implementation code in Matlab for some of the methods as well as other pedagogical aids. Authored by an internationally recognised authority in the area of condition monitoring.

Book Description
This book addresses a range of complex issues associated with condition monitoring (CM), fault diagnosis and detection (FDD) in smart buildings, wide area monitoring (WAM), wind energy conversion systems (WECSs), photovoltaic (PV) systems, structures, electrical systems, mechanical systems, smart grids, etc. The book’s goal is to develop and combine all advanced nonintrusive CMFD approaches on a common platform. To do so, it explores the main components of various systems used for CMFD purposes. The content is divided into three main parts, the first of which provides a brief introduction, before focusing on the state of the art and major research gaps in the area of CMFD. The second part covers the step-by-step implementation of novel soft computing applications in CMFD for electrical and mechanical systems. In the third and final part, the simulation codes for each chapter are included in an extensive appendix to support newcomers to the field.

Book Description
To engineer and manufacture is human. Manufactured goods are subjected to severe international competitive forces. Consumers' perceptions towards total quality, reliable performance, health and safety, environmental issues, energy conservation and cost of ownership are changing day by day. Manufacturers have no alternative but to satisfy the consumer's increasing demands with maximum efficiency and profitability with minimum delay. Failure to meet such a challenge is clearly undesirable and will, no doubt, result in the closure of manufacturing activities, which is still regarded by many as the backbone of our national economy. Manufacturing for profitability should be the number one concern of all serious minded and responsible people. To help the industries to meet these challenges and to manage efficiently well into 1990s and beyond, the Technical Advisory Committee in their wisdom decided the appropriate theme, Profitable Condition Monitoring, for this year's International Conference, to coincide with the great European market to be opened in 1993. The benefits from condition monitoring are well documented. Condition monitoring is now an affordable technology which is waiting to be fully exploited by all sectors of industry, both big and small. Many companies have realised the following benefits from condition monitoring: • optimisation of profits • maximisation of production • cost-effective maintenance • minimisation of product liability • maximisation of total quality. As the contents of this proceedings reveal, there have been a number of significant advances in condition monitoring of which companies ought to be taking full advantage.

Book Description
Condition monitoring of machines in non-stationary operations (CMMNO) can be seen as the major challenge for research in the field of machinery diagnostics. Condition monitoring of machines in non-stationary operations is the title of the presented book and the title of the Conference held in Hammamet - Tunisia March 26 – 28, 2012. It is the second conference under this title, first took place in Wroclaw - Poland , March 2011. The subject CMMNO comes directly from industry needs and observation of real objects. Most monitored and diagnosed objects used in industry works in non-stationary operations condition. The non-stationary operations come from fulfillment of machinery tasks, for which they are designed for. All machinery used in different kind of mines, transport systems, vehicles like: cars, buses etc, helicopters, ships and battleships and so on work in non-stationary operations. The papers included in the book are shaped by the organizing board of the conference and authors of the papers. The papers are divided into five sections, namely: Condition monitoring of machines in non-stationary operations Modeling of dynamics and fault in systems Signal processing and Pattern recognition Monitoring and diagnostic systems Noise and vibration of machines The presented book gives the back ground to the main objective of the CMMNO 2012 conference that is to bring together scientific community to discuss the major advances in the field of machinery condition monitoring in non-stationary conditions.
