From the laboratory to the road, the use of technology as well as further study by engineers is helping to lessen noise, judder, and vibration in cars. This book provides readers with a fundamental understanding of current practices for measuring and testing brake NVH. From coverage of basic definitions and concepts to in-depth analysis of on-road testing procedures, it will serve as a comprehensive reference guide for brake test technicians, test engineers, lab managers, and others who work on making brakes quieter, smoother, more refined, and more reliable. Readers will learn how to test for brake noise, what tools to use, and which recent standards and practices have led to the successful measurement of brake noise and vibration. Topics covered include: • Common brake noise and vibration issues • Instrumentation, transducers, and other technical details • Measurement practice for laboratory and on-road testing • Brake pad damping and natural frequencies • Current trends in brake noise and vibration measurements

Offers practical, no-nonsense coverage, beginning with the fundamentals and moving on to cover specific technologies, applications and legislative details. Provides all the necessary information for specialists and non-specialists to keep up to date with relevant changes and advances in the area.
Featuring contributions from leading experts, the Road and Off-Road Vehicle System Dynamics Handbook provides comprehensive, authoritative coverage of all the major issues involved in road vehicle dynamic behavior. While the focus is on automobiles, this book also highlights motorcycles, heavy commercial vehicles, and off-road vehicles. The authors of the individual chapters, both from automotive industry and universities, address basic issues, but also include references to significant papers for further reading. Thus the handbook is devoted both to the beginner, wishing to acquire basic knowledge on a specific topic, and to the experienced engineer or scientist, wishing to have up-to-date information on a particular subject. It can also be used as a textbook for master courses at universities. The handbook begins with a short history of road and off-road vehicle dynamics followed by detailed, state-of-the-art chapters on modeling, analysis and optimization in vehicle system dynamics, vehicle concepts and aerodynamics, pneumatic tires and contact wheel-road/off-road, modeling vehicle subsystems, vehicle dynamics and active safety, man-vehicle interaction, intelligent vehicle systems, and road accident reconstruction and passive safety. Provides extensive coverage of modeling, simulation, and analysis techniques Surveys all vehicle subsystems from a vehicle dynamics point of view Focuses on pneumatic tires and contact wheel-road/off-road Discusses intelligent vehicle systems technologies and active safety Considers safety factors and accident reconstruction procedures Includes chapters written by leading experts from all over the world This text provides an applicable source of information for all people interested in a deeper understanding of road vehicle dynamics and related problems.
The increase in levels of sophistication and complexity of modern passenger cars and commercial vehicles is being driven by environmental requirements. Braking systems can no longer be considered in isolation - the interactions between vehicle braking, steering, handling, etc., particularly in emergency conditions, are leading to the development of adaptive integrated vehicle control systems. Building upon the success of previous volumes in the series, Braking 2004-Vehicle Braking and Chassis Control reflects the interaction of braking with the whole vehicle. Road vehicle braking behaviour experts, both from academia and industry, present the latest research and development devoted and applied to all aspects of braking, and report on field experiences with modern sophisticated systems. Braking 2004 is essential reading for engineers and researchers from across a wide range of disciplines, from highway engineers and tyre specialists to experts in intelligent control systems, and including, of course the traditional foundation - brake specialists.
