Abstract
A pressure parameter method has been developed for the finite-element solution of Reynolds' equation. Finite-element solutions for bearings typically take a large amount of computer time to run. The pressure-parameter formation utilizing a new variable, which is equal to the pressure times a function of the film thickness raised to arbitrary power, can be applied to improve accuracy significantly. This is particularly true for large eccentricity ratios in journal bearings.
Normally, the finite-element solution of Reynolds' equation is formulated using a functional. With the pressure parameter formulation no functional exits so the Galerkin technique is used in this case. Axial misalignment, turbulent correction factors, and variable viscosity are included in the pressure-parameter formulation. The appropriate element coefficient matrices for the implementation of the Galerkin technique are given to facilitate the use of the methods.
