Overview
I am a Lecturer in Tribology within Cardiff University’s Sustainable Systems and Structures research group.
Tribology is the study of moving contacts (for example contact between gear teeth, or between a wheel and a rail) and the mechanisms of friction, lubrication and wear. My main activities in this field are:
- Research into using Acoustic Emission techniques to provide insight into the mechanisms of gear lubrication and wear. This will help to develop health monitoring methodologies for high value gear transmissions (for example those found in wind turbines).
- Expanding the capability of Cardiff University's state-of-the-art gear simulation software. This has been developed over several decades by successive researchers. It provides deterministic modelling of the lubrication conditions in heavily loaded gears where surface roughness effects are important.
- The study of elastomer tribology, specifically, the factors affecting the performance of dynamic o-rings seals. This interest was initiated by a project investigating the failure of o-ring seals used in high voltage transmission equipment.
- Collaboration with industry to undertake bespoke tribological testing. This often involves the design of novel test rigs and procedures. Previous industrial partners have included small start-ups as well as large companies such as SKF, Rolls Royce and National Grid.
