  3. 2. On the asperity point load mechanism for rolling contact fatigue

    Författare :Johan Dahlberg; Bo Alfredsson; Sören Sjöström; KTH; []
    Nyckelord :Rolling contact fatigue; Spalling; Asperity contact; Point load; Micro-cracks; Traction; Applied slip; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Rolling contact fatigue is a damage process that may arise in mechanical applications with repeated rolling contacts. Some examples are: gears; cams; bearings; rail/wheel contacts. The resulting damage is often visible with the naked eye as millimeter sized surface craters. LÄS MER

  4. 3. Towards accurate modeling of moving contact lines

    Författare :Hanna Holmgren; Gunilla Kreiss; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The present thesis treats the numerical simulation of immiscible incompressible two-phase flows with moving contact lines. The conventional Navier–Stokes equations combined with a no-slip boundary condition leads to a non-integrable stress singularity at the contact line. LÄS MER

  5. 4. Automation in forestry : development of unmanned forwarders

    Författare :Ola Ringdahl; Thomas Hellström; Tomas Nordfjell; Arto Visala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Computer science; Datavetenskap; Forest engineering; Skogsteknik; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. LÄS MER

  7. 5. A New Shoulder for the THOR Dummy Intended for Oblique Collisions

    Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shoulder; Shoulder range-of-motion; Volunteers; Kinematics; Biofidelity; Post Mortem Human Subjects; THOR; Crash test dummy; Oblique collision;

    Sammanfattning : Offset and oblique frontal car collisions represent a type of crash in which severe and fatal injuries frequently occur. This indicates the importance of having protective systems in vehicles for these types of collisions. LÄS MER
