Language(s) of instruction :
|
| French language |
|
Course contents :
|
| Starting from the analysis of the Stribeck curve, we can study the different lubrication regimes (dry, boundary, hydrodynamic, hydrostatic, elastohydrodynamic) and the associated concepts (viscosity, Reynolds equation,...) which allow by an appropriate choice of material, surface treatment, oil, grease,... to try to control the friction and wear phenomena. Two projects, the first being the study of the squeeze film, the second being the study of the thermal behaviour of a lubricated ball bearing allow to practice the theoretical concepts of the course. |
|
Learning outcomes of the course :
|
| Overview of the various types of bearings and lubrication modes: hydrodynamic, hydrostatic and elastohydrodynamic, as well in stationary regime as in non-stationary. Study of basic rheology of greases. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
