  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  3. 2. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  4. 3. Feasibility Study of Energy Harvesting via Biofuel Cell for Miniaturised Implantable Biosensors

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

    Författare :Rebecca Bonato; [2024]
    Nyckelord :Biofuel cell; Blood; Energy Harvesting; Glucose; Power Density; Oxygen;

    Sammanfattning : In the current pursuit of sustainable energy, biofuel cells are attracting considerable attention. Within biomedical engineering, the concept of harnessing energy from biological fluids, such as blood, holds significant promise, enabling both full autonomy and miniaturization. LÄS MER

  5. 4. The Fuel-cell Trucks Ecosystem - Identifying change and strategizing in emerging ecosystem

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Johannes Tröndle; Sendy Setiawan; [2023-07-20]
    Nyckelord :business ecosystem; innovation ecosystem; shaping strategy; ecosystem risks; industry standards; fuel-cell trucks; hydrogen; ecosystem framework; strategic framework;

    Sammanfattning : With the goal to reduce global greenhouse-gas emissions and transportation being a major reason for these emissions, new transportation solutions are needed. One solution is the use of fuel-cell trucks that are powered by hydrogen which are embedded in a young ecosystem. LÄS MER

  7. 5. THIRD HAND : A solution for the fuel tank assembly at Scania Södertälje

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :SandraMarie Westerberg; Tova Ödesjö; [2023]
    Nyckelord :Industrial Design Engineering; Ergonomics; Human-centered design; User-centered design; Safety; Third hand; Automotive; Production; Teknisk Design; Ergonomi; Människocentrerad design; Användarcentrerad design; Säkerhet; Tredje handen; Fordons industri; Produktion;

    Sammanfattning : Scania recently introduced a new fuel tank design. This new design arose a need for extra help when mounting the tank in production, which was solved with two little hooks on each tank. These hooks are today known as the current third hand solution. LÄS MER
