Etude des performances thermoélastohydrodynamiques de paliers soumis à des conditions sévères

Abstract : The aim of this work has been to develop a thermoelastohydrodynamic (TEHD) modelisation by taking into account thermal effects as well as thermal and mechanical deformations. Experimentations have validated this study regardless of whether it is boundary conditions or assumptions which are being considered. Misaligned and worn bearings have been considered. Experimental data have been obtained for various operating conditions including misalignment. A good agreement is found between experimental data and numerical results. The influence of solid displacements on bearing performance has been analyzed under severe operating conditions (large load, high speed, high misalignment torque). Mechanical and thermal deformations were found to be very significant in precisely determining the performance of a bearing subjected to severe operating conditions. In addition, the use of the TEHD model becomes imperative as soon as specific pressure or speed goes over certain acceptable limits.
