摘要
A generalized Reynolds' equation governing power-law non-Newtonian fluids and three dimensional elasticity equations corresponding to realistic three dimensional bearing geometries are numerically solved in this paper. An iterative scheme, which is called the weighted average method here, is used to deal with the iterative convergence of the three dimensional elastohydrodynamic lubrication equations. The scheme is successfully employed in overcoming the difficulty of the convergence at high eccentricity ratios. Inthis work, the influence of flow indices and bearing materials on the performance parameters of elastohydrodynamic lubrication for heavily-loaded finite journal bearings in non-Newtonian fluid are investigated.
