1. Friction in metal powder pressing : measurement and characterisation
Sammanfattning : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. LÄS MER
2. Technical and contractual aspects in winter highway and railway operation and maintenance : a survey of current technical systems and contract forms in Sweden
Sammanfattning : .... LÄS MER
3. On the Multi-Scale Nature of Ski-Snow Friction : Field Testing, Characterisation and Modelling of Cross-Country Ski Performance
Sammanfattning : The goal of most endurance sports is to get from point A to B in the shortest time possible. Throughout the course, athletes need to overcome the resistive forces that are present in their specific sport. LÄS MER
4. Thermomechanics of block brakes
Sammanfattning : Friction in sliding contacts plays an important role in tribology. Applications can be found in many engineering fields such as braking of vehicles in which friction brakes are by far the most common. Thus, an understanding of the mechanisms involved in friction brakes has become more important as the demands on brakes increase. LÄS MER
5. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping
Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER
