  1. 21. Modelling of wear and tribofilm growth

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

    Sammanfattning : 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. LÄS MER

  3. 22. Colliding asperities : a tribological event on micro scale

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

    Sammanfattning : 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. LÄS MER

  4. 23. Interface modeling - friction and wear

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

    Sammanfattning : 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. 24. Friction and wear in rolling and sliding contacts

    Författare :Christer Spiegelberg; Sören Andersson; Roland Larsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; friction; wear; rolling and sliding contacts; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. LÄS MER

  7. 25. Power dissipation in car tyres

    Författare :Martin Fraggstedt; Svante Finnveden; Michael Brennan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. LÄS MER
