The time-varying rolling element bearing characteristics of rotatory system were analyzed. The time-varying form of the stiffness function was characterized and its impact on the vibration response of geared rotor system was calculated. A more generalized formulation based on the Hertzian theory, which relates the raceway displacement vector to the bearing load vector was formulated. The formulation produced a time-invariant nonlinear bearing element for structural analysis of systems with shafts, bearings, and housing.
