Vibration Analysis of Rotor Shaft System using Journal Bearing

摘要: The present work deals with the development of finite element modelling for analysis and study vibration rotor shaft system using journal bearing. composite is mounted an isotropic rigid disk supported by bearings at ends those are modelled as springs viscous dampers. bearing model has been used based on classical Reynolds equation oil lubricated bearings. In this transverse shear deformation, inertia gyroscopic effects due to lamination layers have incorporated. motion shaft-bearing derived method also analysed Timoshenko beam theory. To verify model, critical speeds compared available in literature. Graphs were plotted illustrate frequency displacement response system.
