Substructure synthesis method is employed to the gyroscopic system of a turbo-machine mounted on a table-like foundation. A single-point excitation through a stochastic earthquake process is assumed which is modeled by filtered white noise. The time dependent spectral method is adapted to frequency response functions given in a discrete form. R.m.s.-values of deformations and forces are calculated for spinning and non-spinning rotors, respectively.
