Abstract: This paper deals with the theoretical aspects combined with
experimental analysis regarding early damage identification in passive
vibro-isolation devices. Basically, this research presents the relevant results
obtained for a singular element. Rubber based on elements is discussed
especially. This study was a naturally fall-back of the authors large analysis
regarding the dynamic behaviour of the passive isolation devices against
vibration, shocks and seismic waves. Main hypothesis supposed that on the
exploitation time, all technical devices and systems acquire different levels
of wearing because of the dynamic overloads and their derivative influences
(aging, fatigue, energy dissipation, external heating or cooling, etc.). Hereby
the performance characteristics changes and the system becomes working
improperly. Numerical simulations were developed for simple spatial
configuration of isolation device. Stochastic approach of essential results was
briefly presented nearby the relevant results and discussions.
