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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    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.

  2. 2. Excitation of Tyre Vibrations due to Tyre/Road Interaction

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Frédéric Wullens; [2004]
    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

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Julia Winroth; [2013]
    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

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    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

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    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
