Various models of external fixation of the bushing, including models which take deformation of the fixation itself into account, have been presented in this work. Analysis of static and dynamic properties of the bearing and of the simple rotor-bearing system as dependent on the bush fixation variant has been performed. Investigations on the influence of preliminary assembly of the bush on the system properties have been performed as well. Calculations were based upon a complex thermoelastohydrodynamic model and a special computer program worked out for this purpose. Obtained results point to wide possibilities of improvement of the system properties by optimization of fixation and clamping the bush in the bearing supports.
