FINITE-ELEMENT ANALYSIS OF ELASTOHYDRODYNAMIC STERN BEARINGS

A finite-element analysis is performed for a marine shafting/bearing system utilizing a hydrodynamic, oil-lubricated stern bearing. The stern bearing analysis consists of three-dimensional finite-element analyses of the shafting and the elastic bearing liner, a two- dimensional finite-element analysis of the oil film hydrodynamics, and iterative techniques to establish the equilibrium position between the shaft, the oil film and the bearing material. The results of this analysis are in good agreement with a wide range of experimental data from a stern bearing simulation apparatus.
