Abstract

Dans cet article, les effets combinés de la rugosité de surface et de la rhéologie dulubrifiant additivé sur les performances hydrodynamiques d’un patin plan incliné sontétudiés au moyen de la méthode d’homogénéisation. La surface du patin contiguë au film estsupposée fixe et rugueuse tandis que la surface inférieure mobile est parfaitement lisse.Le modèle de fluide polaire ou à couple de contrainte de V.K. Stokes est adopté pourdécrire le comportement rhéologique du lubrifiant s’écoulant entre les deux surfaces. Lesétudes de simulation sont effectuées en considérant trois formes de rugosités(transversales, longitudinales et anisotropes) et différentes valeurs du paramètre decouple de contrainte. La comparaison des solutions obtenues par les méthodes déterministeet d’homogénéisation a permis de conclure que la méthode d’homogénéisation est efficacepour les trois formes de rugosité envisagées. Les résultats de l’étude paramétriqueeffectuée montrent que les rugosités de surface et les couples de contraintes dus à laprésence des additifs polymériques dans le lubrifiant ont des effets non négligeables surles performances hydrodynamiques du contact, à savoir : le champ de pression, la capacitéde charge, le nombre de frottement et la puissance dissipée.
