Abstract

The subject of the analysis are random vibrations of the beam having uncertain periodic structure. It is assumed that excitation load is described by stationary or nonstationary stochastic process. The parameters of the beam have the uncertain nature and are described by random variables. The problem is solved using the tolerance averaging procedure, the stochastic Green function and the perturbation method. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
