EPSRC funded PhD Studentship - Providing Predictable and Optimised Traction and Braking through Tribo-Chemical Modification of the Wheel/Rail Interface

University of Sheffield

EPSRC funded PhD Studentship with The University of Sheffield and LB Foster Rail Technologies UK Ltd

The initial aim of the project is to provide an understanding of the mechanisms leading to adhesion loss in the wheel/rail contact due to the “wet-rail” phenomenon. This will involve field testing to understand the environmental conditions that lead to the problem occurring and to find out what is happening on the railhead when it occurs. Laboratory tests will then be developed using scaled down laboratory testing right up to tests with our full-scale wheel/rail rig to simulate these conditions and understand how they influence adhesion. Development of appropriate new laboratory testing methodologies will be critical.

Once the causes are understood, the focus of the work will switch to the evaluation of new novel materials and/or methods to provide predictable traction and braking over a range of operating and environmental conditions.

Ideally a student with a strong background in tribology, surface science, physics and / or chemistry is needed, but we can be flexible and training will be given in all areas needed as part of the Doctoral Development Programme run at The University of Sheffield.

The work will involve close collaboration with LB Foster’s Global Rail R&D group and may involve travel to the main centre of LB Foster wheel / rail friction control research activities in Vancouver, Canada.
