ABSTRACT
This chapter introduces the vibration isolation for single- and multi-degree-of-freedom systems and discusses damping, stiffness and mass relationships. It examines types of vibration isolators and describes vibration measurement. The chapter presents damping of vibrating surfaces and looks at measurement of damping. Vibration isolation is considered on the basis that structure-borne vibration from a source to some structure, which then radiates noise, may indeed be as important or perhaps more important than direct radiation from the vibration source itself. Cork is one of the oldest materials used for vibration isolation. It is generally used in compression and sometimes in a combination of compression and shear. When vibration problems occur over a very narrow frequency range, a special-purpose device known as a dynamic vibration absorber may be useful. A vibration neutraliser is of similar construction to a vibration absorber but differs from it in that a vibration neutraliser targets non-resonant vibration whereas a vibration absorber targets resonant vibration.
