Parametric Study for Design Factors on Engine Bearings by using TEHL Analysis

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">As the downsizing and lightening of the engine are designed, the compact and lightweight of the housing should be required. Therefore, both the engine bearing and the housing are greatly deformed under the severe condition, and a heat generation due to the friction loss increases in the bearings.

Multi-dimple phenomena in TEHL point contacts

Science in China Series B, 2002
Theoretical analysis and experimental measurement of the multiple dimples in thermal elastohydrodynamic lubrication (TEHL) point contacts have been carried out. Good agreement is found between the theoretical and experimental results. A thermal multi-spike theory is proposed to explain the multi-dimple phenomena.

Proposed TEHL Solution System for the Thrust Bearings Inclusive of Surface Deformations

Tribology Transactions, 1995
The coupled fluid and solid governing differential equations and their boundary conditions are expressed in dimensionless form which yield dimensionless problem parameters. The proposed solution system uses an efficient hybrid numerical approach. The boundary element method is employed for heat transfer in the pad, a finite difference method for the ...

A Numerical Analysis for TEHL of Eccentric-Tappet Pair Subjected to Transient Load

Journal of Tribology, 2003
A full numerical analysis is carried out to simulate the thermal elastohydrodynamic lubrication (TEHL) of an eccentric-tappet pair. Comparisons between thermal and isothermal results are given to reveal the role of the thermal effect. Under various eccentricities, the influences of two surfaces moving in opposite directions on pressure and film ...

On the prediction of friction coefficient and wear in spiral bevel gears with mixed TEHL

Tribology International, 2017
Abstract A prediction model of the friction coefficient and wear of the spiral bevel gears in the mixed lubrication condition is proposed. Effect of a coupling thermo-elasto-hydrodynamic phenomenon on tooth surface should be considered comprehensively prior to the execution of tooth wear analysis.

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

Applied Mechanics and Materials, 2011
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.
