Abstract

The stability characteristics of 3-axial groove typical water based lubricant available in the market are studied theoretically. These bearings can use lubricant is a new water based biodegradable lubricant. A non–linear analysis of a rigid rotor supported on journal bearings under unidirectional constant load, unidirectional periodic load and variable rotating load is carried out. The time–dependent Reynolds equation in two dimension for incompressible fluid is solved numerically by the finite difference method with a successive over relaxation scheme satisfying the Reynolds boundary conditions, to obtain the hydrodynamic forces. Using these forces, the equations of motion are solved by the fourth–order Runge–Kutta method to predict the transient behavior of the rotor. The analysis gives the orbital trajectory within the clearance circle.
