This book brings together coverage of the theory of railway noise and vibration with practical applications of noise control technology at source to solve noise and vibration problems from railways. Each source of noise and vibration is described in a systematic way: rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise.Theoretical modelling approaches are introduced for each source in a tutorial fashionPractical applications of noise control technology are presented using the theoretical modelsExtensive examples of application to noise reduction techniques are included
Railway Noise and Vibration is a hard-working reference and will be invaluable to all who have to deal with noise and vibration from railways, whether working in the industry or in consultancy or academic research.
David Thompson is Professor of Railway Noise and Vibration at the Institute of Sound and Vibration Research, University of Southampton. He has worked in the field of railway noise since 1980, with British Rail Research in Derby, UK, and TNO Institute of Applied Physics in the Netherlands before moving to Southampton in 1996. He was responsible for developing the TWINS software for predicting rolling noise.Discusses fully the theoretical background and practical workings of railway noiseIncludes the latest research findings, brought together in one placeForms an extended case study in the application of noise control techniques
The authors examine how bullying begins, the impact of bullying on the victimised child, and how the extent of bullying in schools can be reliably measured and assessed. They go on to explain how to set up anti-bullying initiatives which will maintain their effectiveness over the years. The complexity of the bullying process is emphasised throughout, but care is taken to outline clearly the actions that can be taken which will substantially reduce bullying in the long term.
The book is an outcome of over 10 years research into bullying. The authors draw on their own major studies and international research to provide real workable solutions to the problem of bullying, which are illustrated by case study examples throughout. The book is essential reading for school managers, teachers, student teachers and researchers determined to tackle the issues of bullying head on.
9 – 13 September, 2013, in Uddevalla, Sweden. The event, which was jointly organized
by the Competence Centre Chalmers Railway Mechanics (CHARMEC) and the
Departments of Applied Mechanics and Applied Acoustics at Chalmers University of
Technology in Gothenburg, Sweden, covered a broad range of topics in the field of railway
noise and vibration, including: prospects, legal regulations and perceptions; wheel and
rail noise; prediction, measurements and monitoring; ground-borne vibration; squeal
noise and structure-borne noise; and aerodynamic noise generated by high-speed trains.
Further topics included: resilient track forms; grinding, corrugation and roughness;
and interior noise and sound barriers. This book, which consists of a collection of peer-reviewed
papers originally submitted to the workshop, not only provides readers with an
overview of the latest developments in the field, but also offers scientists and engineers
essential support in their daily efforts to identify, understand and solve a number of
problems related to railway noise and vibration, and to achieve their ultimate goal of reducing the environmental impact of railway systems.
As an adult, David Thompson loves returning to his home state of West Virginia, a place full of precious history and recollections. He wishes to share the tenderness and uniqueness of growing up in this state.
This Second Edition of Fundamentals of Sound and Vibration covers the physical, mathematical and technical foundations of sound and vibration at audio frequencies. It presents Acoustics, vibration, and the associated signal processing at a level suitable for graduate students or practicing engineers with having no prior formal training in the field.
The book is a coherent textbook based on the first semester of the master’s program in Sound and Vibration Studies at the internationally acclaimed Institute of Sound and Vibration Research at the University of Southampton.
New in the Second Edition:
The latest edition has been extensively revised and updated, with a new introductory chapter and new chapters on the measurement of sound and vibration. Other chapters include fundamentals of acoustics, fundamentals of vibration, signal processing, noise control, human response to sound and human response to vibration; many of these have been substantially revised. Example problems and answers for self-study are included.
The revised text:
Offers a brief summary on the importance of sound and vibration Considers the vibration of mechanical structures, ranging from simple SDOF models to continuous systems Highlights the aspects of signal processing commonly used for data analysis Addresses engineering noise control, and more
Fundamentals of Sound and Vibration, Second Edition provides you with broad coverage of sound, vibration and signal processing in a single volume, and serves as a reference for both graduate students and practicing engineers.
