Abstract

This paper presents the result of a steady state of thermoelastohydrodynamic lubrication of parallel cylinders in line contact with Newtonian lubricant. The simultaneous system of Reynolds equation, elastic equation and energy equation was solved using Newton-Raphson method and multigrid method. Film pressure, film thickness, film temperature profiles and friction coefficient were determined in the contact region at various loads, speeds and elastic modulus. The simulation results show film thickness and friction coefficient decrease but film pressure and film temperature increase when load and elastic modulus increased. For increasing speeds, film thickness, film temperature and friction coefficient increases.
