Abstract :
The paper considers the computation of moment functions of the
response of large-scale randomly excited vibration systems.
Since standard methods fail because of enormous computational problems
dimension reduction techniques are applied. We find approximations of the
desired response characteristics of the large-scale system by solving a
suitable reduced-order system.
