Stability charateristics of a tri-taper journal bearing: A linearized perturbation approach

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this paper, the stability characteristics of a tri-taper journal bearing is analyzed theoretically. The time dependent form of Reynolds equation in two dimensions for incompressible fluid is solved numerically by finite difference method, satisfying the Reynolds boundary conditions. Dynamic coefficients 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.
