On the analytic representation of the correlation function of linear random vibration systemsGruner, J., Scheidt, J. vom, Wunderlich, R. 30 October 1998 (has links) (PDF)
This paper is devoted to the computation of statistical characteristics of
the response of discrete vibration systems with a random external excitation.
The excitation can act at multiple points and is modeled by a time-shifted
random process and its derivatives up to the second order. Statistical characteristics
of the response are given by expansions as to the correlation length
of a weakly correlated random process which is used in the excitation model.
As the main result analytic expressions of some integrals involved in the expansion terms are derived.
