Abstract
The present work deals with the concept of a stochastic process to solve the problem of isotropic steady-state characteristics of hydrodynamic journal bearings of finite width, considering two types of misalignment, axial (vertical displacement) and twisting (horizontal displacement). Using a finite-difference method, the steady-state film pressures are obtained by solving a Reynolds type equation based on the principle of isotropic roughness pattern. With the help of the steady-state film pressures, the steady-state performance characteristics, in terms of load-carrying capacity, attitude angle, leakage flow-rate, friction coefficient and misalignment moment of a journal bearing with the slenderness ratio of unity, are obtained for various values of isotropic roughness parameter, eccentricity ratio and degree of misalignment.
