Abstract

In this paper, the stability characteristics of a tri-taper journal bearing are analyzed theoretically. The time dependent form of Reynolds equation in two dimensions for incompressible ß uid is solved numerically by Þ nite difference method, satisfying the Reynolds boundary conditions. Dynamic coefÞ cients are determined using the method of linearization of bearing reactions. A study with various ramp size’s and L/D ratio’s predicts that a bearing with higher ramp size and higher L/D ratio results in an increased mass parameter and improved stability margin of the bearing.
