Model Derivation and Numerical Simulation for a Pivoted Rigid Rotor-Bearing System

Abstract:

This work addresses the obtainment of a mathematical model for a rotor-bearing system with orbital movement pivoted on a lubricated bushing. This kind of model allows the rotodynamic system to be analyzed using its angular displacement. Nonlinear dimensionless model is developed in order to present an approach capable of being used in general situations. Both numeric simulations and experimental results, which show the vibration response of the system and the angular orbits, illustrate the validity of the proposed approach.
