1. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction
Sammanfattning : 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. LÄS MER
2. Excitation of Tyre Vibrations due to Tyre/Road Interaction
Sammanfattning : Tyre/road noise is the main contributor to road traffic noise at speeds above 40 km/h for passenger cars and above 70 km/h for heavy trucks. Research has been carried out during the last thirty years in order to understand and quantify the generation mechanisms responsible for tyre/road noise. LÄS MER
3. On the influence of surface roughness on rolling contact forces
Sammanfattning : 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.

4. 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
5. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms
Sammanfattning : Tools for simulating tyre/road noise are highly valuable in the efforts to limit the negative consequences of road traffic noise.A numerical tyre/road noise simulation tool was in this study used to investigate how the contact stiffness parameter affects the predicted tyre/road noise.
