Beschreibung / Abstract

This book discusses the foundations as well as the latest findings and solutions for the isolation and damping of vibrations in automobiles. Starting from the basis of the latest requirements in safety and comfort, it deals with every aspect of automotive vibration control technology – from materials and their development, to product development, construction and production processes, to component and durability testing. Much attention is given to areas of application involving powertrain and chassis technology in passenger and commercial vehicles, such as the properties of engine mounts, and the structure and use of air springs, torsional vibration dampers and mass dampers. The work is aimed at engineers and experts working on development and construction in the automotive production and supply industries; vehicle and special vehicle construction engineers; process engineers and technicians in the elastomer industry; students of vehicle technology, materials sciences and engineering; and anyone with an interest in vibration control technology.
