Damage Detection at Vibration Passive Isolation Devices

Abstract

This paper deals with some theoretical aspects combined with experimental tests regarding early damage identification in vibroisolation devices. This study was a natural fall-back of an analysis regarding the behaviour of the passive isolation devices against vibration and seismic waves. On the exploitation time, all technical devices and systems acquire a different wearing out levels because of the dynamic charging. Hereby performance characteristics change and the system starts working improperly. Rubber based on elements is especially discussed. Numerical simulations were developed for simple spatial configurations of isolation devices. A Stochastic approach of essential results was briefly presented together with relevant results and discussions.
