Análisis Lineal de Cojinetes Hidrodinámicos Utilizando el Método de Mínimos Cuadrados

Abstract

Many researchers have invested their time in creating mathematical models that simulate the dynamic behavior of hydrodynamic journal bearings. In most of the cases a linear model for constant dynamic coefficients have been used. Resent comparisons between the theoretically and experimentally obtained coefficients have not shown the expected agreement. This research present the result of a linear adjustment, of the transient response of the journal-bearing system, perform with the minimum square method. A comparison between this results and the results obtained with an linear analytical methods (i.e. Method of the perturbation about the equilibrium position). permit the establishment of a range were the bearing behave linearly.
