The sealing performance of a hydraulic cylinder depends on the characteristics of three essential elements: the rod, the seal and the fluid. To predict the behaviour of a hydraulic seal, including the friction force and leakage rate, a series of theoretical and experimental studies have been carried out. In this article, a one-dimensional elasto-hydrodynamic model of the U-cup hydraulic rod seal is developed taking into account: the roughness of the shaft and lips. The numerical results are validated by experiments previously published.
Résumé
Les performances d’étanchéité d’un vérin hydraulique dépendent des caractéristiques de trois éléments essentiels : la tige, le joint et le fluide. Pour prédire le comportement d’un joint hydraulique, à savoir la force de frottement et le taux de fuite, plusieurs travaux théoriques et expérimentaux ont été réalisés. Dans le présent article, un modèle unidimensionnel élastohydrodynamique du joint hydraulique en U est réalisé en prenant en compte: la rugosité de l'arbre et des lèvres. Les résultats numériques sont validés par des expérimentations publiées précédemment.
Key words: rod seal / Surface-textured / Roughness / Friction force / Leakage.
Mots clés : Joint hydraulique / Surface texturée / Rugosité / Force de frottement / Fuite.
