  1. 21. Analys av pressresultat vid pressning av ventilstyrningar i cylinderhuvudet : Analysis of press result when pressing valve guides in the cylinder head

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Elise Fransson; Julia Johansson; [2022]
    Nyckelord :;

    Sammanfattning : Examensarbetet har genomförts i samarbete med Aurobay som tillverkar förbränningsmotorer till personbilar. Studien är kopplad till processen där cylinderhuvudet bearbetas och förbereds inför montering. Problematiken som arbetet berörde var pressningen av ventilstyrningar och ventilsäten i cylinderhuvudet.

  3. 22. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Henrik Johansson; [2022]
    Nyckelord :Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Sammanfattning : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. LÄS MER

  4. 23. Conservative Discontinuous Cut Finite Element Methods: Convection-Diffusion Problems in Evolving Bulk-Interface Domains

    Master-uppsats, KTH/Matematik (Inst.)

    Författare :Sebastian Myrbäck; [2022]
    Nyckelord :numerical analysis; mathematical modeling; convection-diffusion equation; partial differential equation; unfitted method; CutFEM; finite element method; discontinuous Galerkin method; numerisk analys; matematisk modellering; konvektions-diffusionsekvationer; partiella differentialekvationer; finita elementmetoden; diskontinuerliga Galerkinmetoden;

    Sammanfattning : This work entails studying unfitted finite element discretizations for convection-diffusion equations in domains that evolve in time. In particular, these partial differential equations model the evolution of the concentration of soluble surfactants in bulk-interface domains. LÄS MER

  5. 24. Assessment of ice loads on piled structures based on local conditions

    Master-uppsats, KTH/Betongbyggnad

    Författare :Astrid Lindblom; Elin Ånger; [2022]
    Nyckelord :Ice loads; Local conditions; Structural design; Piled structures; Islaster; Lokala förhållanden; Dimensionering; Pålade konstruktioner;

    Sammanfattning : This master report studies structural design methods for ice loads and the impact of local conditions. Ice loads occur due to ice movements or expansion of the ice sheet. Specifically, this study analyses ice loads on piled structures and ten different design methods and handbooks to calculate the ice load. LÄS MER

  7. 25. Analysis of Head Kinematics in Ice Hockey

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :David Pogosian; [2022]
    Nyckelord :Ice hockey; Video analysis; MPS; THUMS; Concussion; Head kinematics; Finite Element analysis; Ishockey; Videoanalys; MPS; THUMS; Hjärnskakning; Huvudkinematik; Finita element metoden;

    Sammanfattning : Ice hockey has been identified as a sport with a high risk for concussions due to it being highly physical. Improvements have been made over the years to improve the protective gear for the players effectively eliminating more severe traumatic brain injuries (TBIs) however mild concussions (mTBI) are still prevalent to this day.
