An integrated nonlinear dynamic model of rigid shaft motion, unsteady gas film, and deformations of foil structure is established in order to investigate the impact of external mechanical factors such as sinusoidal and broad-band random vibration of the rotor. The model was verified by experimental data. A notable agreement is demonstrated between the calculation results and experimental data.
