Excitations By An Equivalent Non-linearization
Approach

Abstract
An equivalent non-linearization approach has been implemented in order to find
the response of a beam-stop system subjected to a boundary excitation modelled
as a stochastic process. In particular the original bilinear impact force has been
replaced by a cubic one, whose coefficients have been evaluated by
stochastically minimising the difference between the original and the equivalent
systems. The applications have evidenced an optimum level of accuracy, if
compared with the results of the classical stochastic linearization approach.
1 Introduction
In heat exchangers and nuclear piping systems, baffle plates and snubbers are
used to control large amplitude displacements of tubes due to flow induced or
seismic excitations. These long tubes or pipes expand or contract for the effect of
a temperature change and hence clearances are incorpo
