Finite Element Analysis of Gas-Lubricated Grooved Journal Bearings (Analysis Method)

Abstract

This paper describes the development of a finite element analysis program for the nonlinear and time-dependent Reynolds equation based on an incremental formulation. This program can be utilized to predict the dynamic behavior of gas-lubricated grooved journal bearings. The accuracy of the program is clearly demonstrated through analyses of both non grooved and grooved journal bearings.
