Abstract :
The paper considers the computation of statistical characteristics
of the response of a high-order linear vibration system to a random excitation.
Since standard methods fail because of tremedous computational problems
model reduction techniques are applied. We find approximations of the desired
response characteristics of the high-order system by solving a ``suitable''
low-order system. Numerical results for the torsional random vibrations
of a generator shaft are presented.
