Abstract

Machinery and buildings often have to be protected from vibrations. The needed reduction
of dynamic response can be achieved efficiently with semi-active isolation. One way to use
semi-active isolation is to install vibration isolators between the base and the object to be
protected and control the dynamic properties of these isolators.
The advantage of semiactive isolation compared to passive isolation is the adjustability of the system. With adaptive semi-active isolators it is possible to react simultaneously to the changes of the
loads and dynamics of the system. This paper describes the laboratory tests and the
measurement results of an improved vibration isolator material and an improved adaptive
vibration isolator developed by the Technical Research Centre of Finland (VTT). On the
basis of the results the presented adaptive material and isolator system is applicable for
typical industrial and transportation environments.
