  4. 23. Designing of two load bearing surfaces in a modern high-speed steam engine

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Anders Söderbäck; [2022]
    Nyckelord :Ranotor Modern high-speed steam engine mechanical engineering KISSsoft Bevel gears; Ranotor Ångmotor KISSsoft Maskinteknik;

    Sammanfattning : The topic of this thesis is the designing of two load bearing surfaces in a modern high-speed steam expander. One of the surfaces is a synchronizing gear structure and the other a conical surface. The goal besides the design is to calculate the contact pressure these surfaces experience during operation.

  5. 24. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Huanyu Chen; [2022]
    Nyckelord :CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

    Sammanfattning : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

  7. 25. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Gustav Thessén; [2022]
    Nyckelord :µ-CT modelling; phase-field method; bio-glass scaffolds; strength assessment; Mikrotomografi; μ-CT; fasfältsmetoden; bio-glas stödstrukturer; brottgräns;

    Sammanfattning : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.
