Journal bearings subjected to dynamic loads : the analytical mobility method

The main purpose of this work is to use the analytical mobility method to analyze journal bearings subjected to dynamic loads, with the intent to include it in a general computational program that has been developed for the dynamic analysis of general mechanical systems. A simple journal bearing subjected to a dynamic load is chosen as a demonstrative example, in order to provide the necessary results for a comprehensive discussion of the methodology presented.Fundação para a Ciência e a Tecnologia and partially financed by Fundo Comunitário Europeu FEDER under project POCTI/EME/2001/38281, entitled ‘Dynamic of Mechanical Systems with joint Clearances and Imperfections
