  3. 2. Initiation of rolling contact fatigue from asperities in elastohydrodynamic lubricated contacts

    Författare :Carl-Magnus Everitt; Bo Alfredsson; Stefan Björklund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spalling; Pitting; Slip; Elastohydrodynamic; Thermal elastohydrodynamic; Fatigue; Contact mechanics.; Pitting; Glidning; Elastohydrodynamik; Termisk elastohydrodynamik; Utmattning; Kontaktmekanik.; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Rolling contacts are utilized in many technical applications, both in bearings and in the contact between gear teeth. These components are often highly loaded, which makes them susceptible to suffer from rolling contact fatigue. This work focuses on the rolling contact fatigue mechanism of pitting. LÄS MER

    Författare :Carl-Magnus Everitt; Bo Alfredsson; Andreas Almqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact mechanics; Rolling contact fatigue; Pitting; Spalling; Slip; Thermal elastohydrodynamic.; Kontaktmekanik; Rullande kontaktutmattning; Pitting; Glidning; Termisk elastohydrodynamik.; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Rolling contacts are utilized in many technical applications, both in bearings and in the contacts between gear teeth. These components are subjected to high loads in many of their applications. The high loads causes very high contact pressures which may cause rolling contact fatigue, often denoted as pitting or spalling. LÄS MER

  5. 4. Supply chain visibility in the manufacturing industry: conditions and realisation

    Författare :Ravi Kalaiarasan; Magnus Wiktorsson; Jannicke Baalsrud Hauge; Carl Wänström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; supply chains; supply chain visibility; technologies; supply chain management; försörjningskedjor; synlighet i försörjningskedjor; teknologier; supply chain management; Production Engineering; Industriell produktion;

    Sammanfattning : Supply chain visibility (SCV) has been gaining attention as a key for supply chainperformance. The key characteristics of SCV are information accessibility, accuracy,timeliness, completeness and usage, all of which aid in the enhancement ofoperational and strategic supply chain activities.
