Purpose - to develop new theoretical and experimental studies of high-speed vibration characteristics of rotor systems in the combined magnetic or liquid bearings in a gaseous working fluid loading with non-uniform physical properties, cyclic loading, uneven, given the defects and damages. Identify new patterns of influence of small random process variations on vibration characteristics of the impellers. A new technique for modeling rotor system for liquid bearings based on the condensation approaches the finite element method and algorithm for calculating linear and nonlinear deterministic oscillations with allowance for defects. For the first time the technique of mathematical modeling of the dynamics of rigid rotor in magnetic bearings, and an algorithm for the numerical analysis of the motion of the rotor.
