  1. 31. How Does Skid Design Affect Transportability and Handling of Heavy Machinery?

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Eric Eldensjö; Isidor Söderman-Lundqvist; [2022]
    Nyckelord :skid mounted machinery; transportability; FEA; lashing and securing; load carrier.; rammonterad maskin; transporterbarhet; FEM-analys; surrning och säkring; lastbärare;

    Sammanfattning : At request of the company Climeon, this study was made regarding transportability of skid mounted heavy machinery. The study aimed to investigate what constraining dimensions there might be when transporting by road and sea as well as necessary features that would accommo date lifting, handling, lashing and securing.

  3. 32. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Jonathan Fridstrand; [2022]
    Nyckelord :Torsion; Shear stress-strain relation; Elastoplastic material; Case hardened steel; Custom material model; Vridning; Skjuvtöjning och -spänning; Elastiskt-plastiskt material; Sätthärdat stål; Anpassad materialmodell;

    Sammanfattning : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. LÄS MER

  4. 33. 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

  5. 34. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Luis Alfonso Penela Guerrero; [2022]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Sammanfattning : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. LÄS MER

  7. 35. Simulation of load capacity of 3D printed concrete patterns

    Master-uppsats, KTH/Betongbyggnad

    Författare :Magnus Burton; Karolina Näsén; [2022]
    Nyckelord :;

    Sammanfattning : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. LÄS MER
