  2. 1. Rough surface elastohydrodynamic lubrication and contact mechanics

    Author : Andreas Almqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : In the field of tribology, there are numerous theoretical models that may be described mathematically in the form of integro-differential systems of equations. Some of these systems of equations are sufficiently well posed to allow for numerical solutions to be carried out resulting in accurate predictions. READ MORE

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

    Author : Patrik Andersson; Chalmers tekniska högskola; []
    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

  6. 4. Numerical models to simulate wear and friction-induced heating in rough surface contacts

    Author : Jamal Choudhry; Roland Larsson; Andreas Almqvist; Ramin Aghababaei; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : The study of friction and wear is a crucial element in the effort to reduce carbon footprint in technology. It is evident that friction and wear are responsible for a significant amount of global energy losses, emphasizing the need for research on the topic. READ MORE

  7. 5. Colliding asperities : a tribological event on micro scale

    Author : Shaojie Kang; Stefan Björklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : In order to predict and optimize energy efficiency, fuel consumption and service life, friction and wear need to be predetermined with higher accuracy than what is possible today. This prediction and optimization is crucial for the development of sustainable mechanical components and systems with excellent environmental performance. READ MORE
