From comperison with the experiment, it may be concluded that the influence on the dynamic characteristics should be considerable when the kinematic viscosity of the lubricant becomes too low, and that the presented analysis yields good predictions for both the bearing stiffness and the damping coefficient in a wide range of designing conditions.
