1. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance
Abstract : Increased fuel consumption, increased greenhouse gas emission, diminishing real-estate prices and increased health issues are some of the negative effects on the climate, on the environment and on the society from tyre/road rolling resistance and noise. The first two aspects are affected by energy dissipation in the tyre/pavement contact and are related to rolling resistance. READ MORE

2. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms
Abstract : 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.

3. Excitation of Tyre Vibrations due to Tyre/Road Interaction
Abstract : 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. 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

5. Dynamic contact stiffness and air-flow related source mechanisms in the tyre/road contact
Abstract : Two aspect of phenomena occurring in, and in the vicinity of the contact patch formed by a tyre rolling on a road are here investigated: 1. A detailed numerical time domain contact model is used to evaluate approximations of the tread response that are commonly embraced in tyre/road interaction models. 2. READ MORE
