Stochastic Systems with Distributed Parameters
The contribution is devoted to multispanned panel systems consisting of one-dimensional structure elements under a stationary random excitation assumed to be uncorrelated in space and time. Up to now, the dynamic response of such distributed systems is investigated by means of discretization methods using a normal mode approach or local approximations by finite elements. Since these methods principally lead to infinte series of coupled equations of motion, there is an enormously increasing requirement in the numerical evaluation and the identification procedure.
