  1. 1. Tyre/road interaction A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance

    Author : Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Tony Parry; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; surface; noise; rolling resistance; tyre; mitigation; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Building Materials; Byggnadsmaterial;

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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Julia Winroth; [2017]
    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.

  3. 3. Modelling Interfacial Details in Tyre/Road Contact — Adhesion Forces and Non-Linear Contact Stiffness

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Patrik Andersson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rough surface; tyre dynamics; tyre road noise; adherence force; adhesion forces; tyre road interaction; dynamic contact; non-linear contact stiffness;

    Abstract : 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. READ MORE

  4. 4. The influence of modelling parameters on the simulation of car tyre rolling losses and rolling noise

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Carsten Hoever; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling resistance; modelling parameters; parameter study; radiation; tyre road noise; tyres; tyre road interaction; waveguide finite element;

    Abstract : Due to legislative changes within the EU there is an increased demand for improvement in car tyre rolling resistance and noise generation. Yet, apart from empirical data based on measurements, there is little information concerning the relationship between rolling resistance and rolling noise generation. READ MORE

  5. 5. Tyre-road Interaction: a holistic approach to noise and rolling resistance

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Tiago Vieira; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement; surface; texture; noise; rolling resistance; tyre; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Energy dissipation, fuel consumption, real-estate property prices and health issues are some of the aspects related to the tyre/pavement interaction and its functional properties of rolling resistance and noise. The first two aspects are affected by the tyre/road interaction as energy is dissipated mostly by hysteretic losses as the tyre is subjected to dynamic deformations when contacting the pavement surface.
