  1. 21. Cooling simulation of a BEV electrical machine rotor

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Lisa Sparv; [2021]
    Nyckelord :Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Sammanfattning : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. LÄS MER

  3. 22. Deflection measurements with 3D close range photogrammetry

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guillaume Defromont; [2021]
    Nyckelord :Photogrammetry; Computer Science; Optimization; Aero-elasticity; Fotogrammetry; Datvetenskap; Aeroelasticitet;

    Sammanfattning : Photogrammetry is a great technology to check and track deformations on anysurface. This information is critical in many tranportation industries such as aeronautics and the automotive industry. In this thesis report photogrammetry measurements were done using 2 Aicon cameras providing 3D targets coordinates. LÄS MER

  4. 23. Investigation of sources of wheel-rail impact force deviation through dynamic simulations

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Sumanth Ram Aravindababu; [2021]
    Nyckelord :Multi-body simulations; wheel damages; rail damage; damage thresholds; wheel-rail impact forces; classification; Flerkroppssimulering; hjulskador; rälskador; skadetrösklar; hjulslagkraft; rälslagkraft; klassificering;

    Sammanfattning : Due to the increase in demand on freight transportation it becomes necessary to avoid delays to ensure that the goods reach its destination on time. The main factors causing disturbances in the traffic on the mainline is the breakdown of vehicles mainly due to damaged wheels. LÄS MER

  5. 24. Tank-to-Wheel Energy Breakdown Analysis

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Xu Yu; [2020]
    Nyckelord :Hybrid electric vehicle; Energy analysis; Sankey diagram; Vehicle simulation; Energy management system; Driving pattern recognition; Plug-in hybrid; energianalys; Sankey diagram; fordonssimulering; energihanteringssystem; detektering av körbeteende;

    Sammanfattning : In early design phase for new hybrid electric vehicle (HEV) powertrains, simulation isused for the estimation of vehicle fuel consumption. For hybrid electric powertrains,fuel consumption is highly related to powertrain efficiency. LÄS MER

  7. 25. HEV thermal management of high voltage battery with indirect air cooling and regarding customer performance

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Benjamin Ortéga; [2020]
    Nyckelord :;

    Sammanfattning : The automotive environment is quickly evolving due to increasingly stringent environmentalstandards and the gradual reduction of the volume of diesel motorized vehicles. The volumes of electrifiedvehicles are thus constantly growing and are brought to be more and more present in our streets. LÄS MER
