Modélisation des pertes de puissance d’engrenages spiro-coniques lubrifiés par bain d’huile : Application à une boîte de transmission arrière d’hélicoptère
Autor: Quiban, Romain
Publikováno v: Mécanique [physics.med-ph]. Université de Lyon, 2020. Français. ⟨NNT : 2020LYSEI066⟩
The current environmental context is driving the aeronautic industry towards new design criteria. On the one hand, governments demand emission reductions of pollutants and on the other hand, customers, i.e. aircraft manufacturers, are pushing to redu

Etude de l'indentation et de la fatigue des contacts roulants
Autor: Bonetto, Alexis
Publikováno v: Mécanique [physics.med-ph]. Université de Lyon, 2020. Français. ⟨NNT : 2020LYSEI030⟩
Surface fatigue is currently the main cause of rolling element bearings failures. This type of fatigue can appear due to the presence of surface asperities but is exacerbated by the presence of surface defects such as dents. Handling the contaminatio

Prédiction du frottement pour les surfaces rugueuses dans un contact lubrifié élastohydrodynamiquement
Autor: Zhang, Yuanyuan
Publikováno v: Materials and structures in mechanics [physics.class-ph]. Université de Lyon, 2019. English. ⟨NNT : 2019LYSEI063⟩
The friction of interfacial surfaces greatly influences the performance of mechanical elements. Friction has been investigated experimentally inmost studies. In this work, the friction is predicted by means of numerical simulation under an elastohydr

A molecular approach to the ultimate friction response of confined fluids
Autor: Porras Vazquez, Alejandro
Publikováno v: Fluids mechanics [physics.class-ph]. Université de Lyon, 2019. English. ⟨NNT : 2019LYSEI087⟩
In order to control energy losses in mechanical systems, a thin film of lubricant is often introduced between the solids in contact. The lubricated point contacts operate in the elastohydrodynamic regime, characterized by high pressures (of the order

Particle entrapment in EHD contacts - Aerospace applications

Une lubrification suffisante est essentielle au bon fonctionnement des mécanismes et/ou composants comme par exemple les paliers à roulement. Par contre, les lubrifiants contiennent souvent des débris d’usure ou des polluants extérieurs. Ces pa

Contact lubrication is essential in a wide range of mechanical systems like rolling element bearings (REBs). A minimum quantity of clean lubricant all along the bearing life is necessary but difficult to ensure. In fact, lubricants contain inevitably
