1. Vibrations induced by surface roughness in nonlinear rolling contacts
Abstract : For efficient transportation in either trains, busses or passenger cars, rolling elements such as wheels, tyres, bearings and transmission elements are fundamental. The energy efficiency and the generation of noise and vibrations in rolling contacts depend on the surface roughness of contacting bodies. READ MORE

2. On the influence of surface roughness on rolling contact forces
Abstract : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.

3. On wear in rolling/sliding contacts
Abstract : The aim of this thesis is to increase the understanding of wear in rolling/sliding contacts such as the wheel-rail contact for railroads and the roller-washer contact for roller bearings. The Stockholm commuter train network has been the subject of papers A and B in this thesis in which the wear and surface cracks on rails has been observed for a period of three years. READ MORE

4. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction
Abstract : Noise is a severe problem in modern society. Road traffic noise is a substantial contributor and the tyre/road interaction is the main noise source for normal driving conditions. Despite more than 30 years of research, there is a lack of quantitative tyre/road noise prediction models. READ MORE
