In this paper the energy flow confidence between two structural multimodal systems coupled by a joint with uncertain parameters is computed by two different methods. The first one assumes that the joint parameters perturbed randomly: the statistical moments of the energy flow are calculated by an analytical procedure. The second one uses interval analysis. The joint parameters are considered interval variables and the interval of the energy flow is determined. The properties of the statistical and interval solution are investigated and compared.

Abstract
In this paper the energy flow confidence between two structural multimodal systems coupled by a joint with uncertain parameters is computed by two different methods. The first one assumes that the joint parameters perturbed randomly: the statistical moments of the energy flow are calculated by an analytical procedure. The second one uses interval analysis. The joint parameters are considered interval variables and the interval of the energy flow is determined. The properties of the statistical and interval solution are investigated and compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
