  2. 11. Lubrication mechanism of hydrocarbon-mimicking ionic liquids

    Author : Erik Nyberg; Ichiro Minami; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; P-SiSO; boundary film; silicate; friction; wear; anti-wear; friction modifier; base fluid; Maskinelement; Machine Elements;

    Abstract : Lubrication is critical in order to achieve high efficiency and reliability of machine elements such as gears, bearings, and other moving mechanical assemblies (MMA). In space applications, tribological properties of lubricants are quickly growing more important. READ MORE

  4. 12. Elastohydrodynamic Lubrication of Cam and Roller Follower

    Author : Mohammad Shirzadegan; Jonas Ståhl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Modelling and simulation of friction is a research issue that still requires an extensive amount of input from the scientific community. In a lubricated system, the dissipation of energy is connected to the direct contact between the surfaces, or more precisely the tribofilms, as well as of the shearing of the lubricant film.

  5. 13. Lubrication, contact mechanics and leakage between rough surfaces

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

    Abstract : Mechanical components with interacting surfaces are central in everyday life. Interactions between surfaces, such as the sliding, rolling and bouncing, on one another may be found everywhere. These surfaces are often required to withstand severe conditions resulting in wear, which may ultimately lead to failure. READ MORE

  6. 14. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction

    Author : Mohammad Shirzadegan; Daniele Dini; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. READ MORE

  7. 15. On the effects of surface roughness in lubrication

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

    Abstract : Tribology is a multidisciplinary field defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication. A typical tribological application is the rolling element bearing. READ MORE
