1. Modelling Interfacial Details in Tyre/Road Contact Adhesion Forces and Non-Linear Contact Stiffness
Sammanfattning : Rolling resistance, noise generation, and wear are all determined by the interaction process between the rolling automotive vehicle tyre and the road. A deep understandingof the interaction process is needed for optimisation aiming at reducing these effects. LÄS MER
2. Investigation of Forces and Contact Area for Modelling Turning Processes
Sammanfattning : This thesis is focused on an investigation of forces andcontact area for modelling turning processes. The primary taskin short term research has been to take a first steptowards animproved model of the cutting process. LÄS MER
3. Thermally stable electrical contacts to 6H silicon carbide
Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform. Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions. LÄS MER
4. Rough surfaces in contact : artificial intelligence and boundary lubrication
Sammanfattning : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. LÄS MER
5. Analysis and Applications of Minimum Quantity Lubrication (MQL)
Sammanfattning : One of the greatest obstacles to the implementation of MQL is “lack of knowledge” which also limits the expansion of its usage. The presented work aims to take a step toward a better understanding of the mechanisms that occur in MQL assisted machining. LÄS MER
