1. Diesel Engnine Cam and Roller Follower Tribology
Abstract : Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. READ MORE

2. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction
Abstract : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. READ MORE

3. Elastohydrodynamic Lubrication of Cam and Roller Follower
Abstract : Modelling and simulation of friction is a research issue that still requires an extensive amount of input from the scientific community. In a lubricated system, the dissipation of energy is connected to the direct contact between the surfaces, or more precisely the tribofilms, as well as of the shearing of the lubricant film.

4. Wear resistant low friction coatings for engine components
Abstract : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. READ MORE

5. Transient elastohydrodynamic lubrication : Effects of geometry, surface roughness, temperature, and plastic deformation
Abstract : The urgent need to reduce greenhouse gas emissions in combination with an increased use of sustainable energy resources have led to immense efforts on improving energy efficiency of mechanical systems. Consequently, modern machine elements are typically lubricated with low viscosity oils and designed to endure an increasingly high power density. READ MORE
