DYNAMIC STIFFNESS CHARACTERISTICS OF HIGH ECCENTRICITY RATIO BEARINGS AND SEALS BY PERTURBATION TESTING

摘要

In prior work perturbation methodology was done to describe the behavior of lightly loaded bearings or seals. This work helped to clarify the stiffness algorithms and to show the algorithm of the fluid inertia effect. This paper takes up the much more complex behavior of cylindrical bearings and seals that are statically loaded to eccentricities in excess of 0.7. The stiffness algorithms as a function of static load are developed from perturbation methodology by empirical modeling.
