The authors investigated the response to an earthquake of magnitude up to 9 points for the two schemes of stationary gas turbine unit (GTU): with a heavy rotor in full plain bearings and a flexible rotor in journal bearings with self-aligning pads, and shoe-type bearings. The orbits of the rotor and the deformation of body parts in stationary and during the seismic impact are determined, that allowed to estimate the change of clearances in the gas-dynamic channel and bearings, and make a conclusion for GTU on capacity for work under seismic impacts.
