Preamble: Questions to the holders of the chair

SKF Aerospace, a company belonging to the SKF Group specialised in bearings and lubrication systems for the aerospace industry, and INSA Lyon announce the creation of a Teaching and Research Chair dedicated to the study of lubricated interfaces, as part of the sponsorship programme run by the Foundation of INSA Lyon.

1. a theme at the heart of today’s technological and industrial challenges

The overall, underlying challenge of this Chair, in the field of lubrication, is to respond to technological,environmentalandeconomic issuessuchas: increasing lifespans,decreasingenergy losses, reducing theuseoffossil-basedmaterials,andreducingthecostsforthedesignandoperationofmechanicalsystems.

Consequently, the scope of the Chair covers several issues in the field of lubricated interfaces to identifysolutions for the future, for example bearings, joints and screw systems. In this context, lubricants (oftencomplex fluids due to their nature and composition) play a crucial role in reducing friction losses and inreducing the risk of damage. They are subject to severe stress of different types: pressure gradients andconfinement,temperatureincrease,intenseshearingforces,interactionwiththeenvironment,etc.

ThroughthisChair, it isthereforevitalfortheSKFGroup-aworldleaderinthesupplyofbearings,seals,mechatronics,lubricationsystemsandrelatedservices-todevelopitsunderstandingonhowlubricantsmeetthesedemands,tobeabletomodelitsresponseandintegratethisinsimulationtools,therebyenablingthecompanytoimprovelubricantspecificationaccordingtotheapplication.
