1. New insights into lubricated tribological contacts
Abstract : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. READ MORE

2. Grease in elastohydrodynamic lubrication
Abstract : The rheology of soap thickened greases has been investigated in a cone and plate rheometer and a model that includes base oil viscosity and temperature has been suggested and fitted to the results. With the use of a bouncing ball apparatus, the pressure coefficient of the limiting shear stress of the greases was determined. READ MORE

3. Design, testing and analysis of journal bearings for construction equipment
Abstract : Grease-lubricated journal bearings present a common challenge for construction equipment manufacturers in the world. The common design methodology is based on empirical data and has worked very well historically because the market and governments have accepted that bearings in construction equipment need frequent lubrication and exchange of worn parts.
