Abstract
Hydrodynamic journal bearings are critical power transmission components which carry high loads. Therefore, knowing the true operating conditions of hydrodynamic journal bearings is essential to machine design. Oil film pressure is one of the key operating parameters describing the operating conditions in hydrodynamic journal bearings. In the analysis of fluid-film bearings the basic equation employed is known as the Reynolds equation. Using Reynolds equation, one-dimensional analysis is done for plane tilted pad and journal bearing conventionally. Finite Difference approach is used to solve the Reynolds equation for plane tilted pad and journal bearing (one dimensional and two dimensional). Various approaches like Gauss elimination, Gauss–Seidel, Liebmann with Over-relaxation are applied to solve the equations produced on implementing Finite Difference method. Following same methodology, a special case of deformed shaft (elliptical geometry) has been studied.
