  1. 1. Compressor Surge: Simulation, Modeling and Analysis

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Robin Massiquet; [2022]
    Nyckelord :Turbo compressor; Surge; Simulation; Modelling;

    Sammanfattning : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. LÄS MER

  3. 2. Design and evaluation of a shock load resistant dynamic chain plate

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Olsson; [2022]
    Nyckelord :Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Sammanfattning : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. LÄS MER

  4. 3. Sandwich Design of a Platform Lift Floor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ruizhi Zhao; [2022]
    Nyckelord :Aluminium honeycomb sandwich; Fatigue analysis; Sandwich design; Sandwich joint design; SolidWorks simulation; Bikakesanalys; Bikakemönster sandwich; Sandwich design; SolidWorks-simulering; Utmattningsanalys;

    Sammanfattning : Mobility is a symbol of dignity. A platform lift enables everyone of different physical abilities to move vertically with ease. Currently, the platform lift by Aritco Lift is made of steel sheet metal. It is heavy, thus difficult to handle. LÄS MER

  5. 4. Fatigue analysis of laser welded hairpins in electric car motors

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
    Nyckelord :;

    Sammanfattning : Hairpins are copper filaments used in the windings in the stators of electric motors in modern times. For the motor to work, they have to be welded in pairs, normally with laser welding. Studying the fatigue response of the joint of hairpins welded with a set of values of laser welding process parameters is the main objective of this project. LÄS MER

  7. 5. A comparison of pressurised cylinders in HIP systems using CFD and FEM

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lisa Lindqvist; [2021]
    Nyckelord :Hot isostatic pressing; HIP; Pressure vessel; Monoblock; Axisymmetric; FSI;

    Sammanfattning : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. LÄS MER
