Summary: The work focuses on the adequacy of predictive models of behavior Vibrating machinery with flexible rotors in industrial plants, which in their working conditions show a lack of linearity in the vibrational response, and that are supported on breaks hydrodynamic . Bearing the need for a reliable and complete mathematical model in predicting behavior dinámico-vibratorio, develops a theoretical model, platform language programming in MatLab, introducing calculating rigidities and amortiguamientos during breaks hydrodynamic lubrication of wider use; they then conducted an analysis to solve the differential equation of the vibrational response of the rotor acting on the rest of hydrodynamic fluid. In modulating the rest hydrodynamic, it is considered the effect of stiffness and damping coefficients which provides fluid to be compressed by the weight of the rotor when it operates under a load of desbalanceamiento generated by an external force. The study considering his eight coefficients, which are four of rigidities and four amortiguamientos (direct and Crusaders), non-linear, which are considered in order to obtain the vibrational response.
