My aim is to provide advanced tribological expertise and solutions for developing future design concepts for machine elements such as gears, bearings and frictional joints to improve their performance and service life. This work is done with close collaboration with industry using high standard numerical and experimental methods.
Tribology and machine elements such as gears, bearings and frictional joints (fretting)
Materials Science and Environmental Engineering
My research focus is on tribology, which investigates the friction, wear and lubrication of contacting surfaces as well as related fundamental failure mechanisms. This gives basis for the analysis and dimensioning of machine elements and systems in terms of their performance and service life. The research topics are typically derived from real industrial problems. Theoretical research concentrates on numerical modeling and simulation of dry and lubricated contacts targeted at various applications. Experimental work is carried out for the verification of the models as well as for the testing and monitoring of real applications. Special interest is focused on determining the micro-scale contact effects on macro-scale designs. Main applications are frictional joints (fretting), bearings and gears related to, for example, combustion engines, mineral crushers and gear drives in wind turbines and marine applications. Advanced tribological contact design improves energy efficiency, power density and reliability of machine elements and systems having essential contribution to Finnish industrial competiveness.
