11. Tribology in Metal Working
Sammanfattning : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. LÄS MER
12. Torsional vibration absorbers in heavy-duty truck powertrains
Sammanfattning : The heavy-duty vehicle manufacturers face large challenges when it comes to reducing CO2 emissions from vehicles. The ongoing development of more efficient combustion engines leads to an increase in torsional vibrations. LÄS MER
13. Dual mass flywheels in truck powertrains, Modelling, simulations and validation
Sammanfattning : The heavy-duty vehicle manufacturers face large challenges when it comes to reducing CO2 emissions from vehicles. The on-going development of more efficient combustion engines leads to an increase in torsional vibrations. LÄS MER
14. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature
Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. LÄS MER
15. Wet clutch tribology : friction characteristics in limited slip differentials
Sammanfattning : In recent years, electronically controlled automotive transmission systems, where wet clutches are used as intelligent differentials, have appeared in the market. These applications impose great demands on the transmission fluids and friction materials used as well as on controllability and vibration preventive (anti-shudder) properties of the clutch systems.
