  1. 1. Rough surfaces in contact : artificial intelligence and boundary lubrication

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

    Abstract : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. READ MORE

  2. 2. 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

  3. 3. Modelling of wear and tribofilm growth

    Author : Joel Andersson; Rob Bosman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Wear is a consequence of nature which becomes costly if uncontrolled. Basic wear protection is provided by lubrication which will decrease the severity of the contact between asperities. READ MORE

  4. 4. Interface modeling - friction and wear

    Author : Anders Söderberg; Sören Andersson; Norbert Huber; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfaces; Models; Simulation; Friction; Wear; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : The general trend toward increased use of computer models and simulations during product development calls for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. Simulating the behavior of such products requires accurate models of both components and interfaces.

  5. 5. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions

    Author : A. Elisabet Horvath; Lars Wågberg; Stefan Zauscher; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adsorption; electrolyte; polyelectrolyte; polyelectrolyte titration; stoichiometry; fluorescence; CLSM; carboxymethylation; ESCA; charge ration; colloidal interactions; mechanical forces; network strength; floc; CPM; rehometer; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The surface charges of cellulosic fibers contribute to several papermaking operations that influence the manufacture and final properties of paper. This thesis investigates the effect of the surface charges on wet-end chemistry, e.g. READ MORE
