Analysis of Two Surfaces in Line Contact under TEHL with Non-Newtonian Lubricants

Abstract:

This paper presents the static characteristics of two surfaces in line contact under TEHL with non-Newtonian lubricant. Modified Reynolds equation, elastic equation and energy equation were formulated to obtain the model. The model was simulated based on numerical method by using Newton-Raphson and multigrid multilevel techniques. The static characteristics of the two surfaces in line contact under TEHL such as film pressure, film thickness and film temperature profiles in the contact region were examined at various loads, speeds, roller radius and elastic modulus respectively. The results showed the significant effect of load, elastic modulus and surface velocity on the TEHL for machine element operated at severe conditions.
