  1. 1. Elastohydrodynamically lubricated finite line contacts operating under transient conditions

    Författare :Tobias Hultqvist; Roland Larsson; Lars-Erik Stacke; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The effect of greenhouse gas emissions contributing to the global warming is today becoming an increasingly important problem worldwide and has led to increased efforts being made on improving tribological performance of interacting surfaces in mechanical systems. Due to increasingly stringent CO2regulations, a reduced fuel consumption has become a key area of interest for the automotive industry where low cost, low emission solutions are continuously developed and where low friction alternatives to machine elements currently in use are evaluated.

  3. 2. Monitoring of wear in elasto- hydrodynamic lubricated contacts : Running-in and failure propagation

    Författare :Stephan Schnabel; Lars-Erik Stacke; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Elasto-hydrodynamic lubricated (EHL) contacts can be found in various machine elements or systems, like rolling element bearings, cam followers or gear transmissions. The service life of these elements and systems are depending to some extent on the performance of EHL contacts. LÄS MER

  4. 3. On interface modeling  with emphasis on friction

    Författare :Anders Söderberg; Sören Andersson; Lars-Erik Stacke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface model; contact; friction; simulation; system behaviour; surface roughness; elastic foundation; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The general trend toward increased use of computer models and simulations during product development has led to a need for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. LÄS MER
