2. 1. High Frequency Tyre Vibrations

   Author : Patrik Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local deformation; adhesion; tyre model; air pumping; parameter study; tyre road noise; tyre road prediction models; tyre noise;

   Abstract : High frequency (above 1 kHz) noise generation from the tyre/road interaction is still not fully understood and accurately modelled.Two noise generation mechanisms previously suggested in the literature are reviewed: air pumping and noise generation cased by adhesive effects between the tyre tread and road surface.

4. 2. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction

   Author : Krister Larsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tyre dynamics; rolling noise; rolling contact; dynamic contact; tyre road noise; 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. 3. Excitation of Tyre Vibrations due to Tyre/Road Interaction

   Author : Frédéric Wullens; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tyre road interaction; tyre road noise; tyre structure modelling; contact modelling;

   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

6. 4. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms

   Author : Julia Winroth; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tyre road noise; Air-pumping; Tyre road contact stiffness; Speed exponent analysis; Tyre road contact modelling;

   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.

7. 5. Dynamic contact stiffness and air-flow related source mechanisms in the tyre/road contact

   Author : Julia Winroth; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tyre road noise; Tread modelling; Air-flow related source mechanisms; Air pumping; 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
