  1. 1. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Simon Garpenquist; [2023]
    Nyckelord :Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Sammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Isabelle Gürsac; Tsimafei Klimantovich; [2023]
    Nyckelord :Bidirectional vehicle; 4WS; 4WD; suspension angles; kingpin inclination; camber angle; caster angle; toe angle; relative importance; suspension setup; suspension system; drivetrain; efficiency.; Dubbelriktat fordon; fyrhjulsstyrning; fyrhjulsdrift; hjulvinklar; Kingpin-lutningsvinkel; cambervinkel; castervinkel; toevinkel; relativ betydelse; fjädringsinställning; hjulupphängningssystem; drivlina; effektivitet.;

    Sammanfattning : The bidirectionality of road vehicles is a novel research area, which is directly connected with autonomy, efficiency, flexibility and sustainability of transportation. The research in this area is mostly performed with stringent restrictions in corporate secrecy. This fact makes the area publicly unexplored, moreover highly future oriented. LÄS MER

  4. 3. Reglering av aerodynamiska element för lätta fordon

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Jonathan Rendel; William Balte; [2022]
    Nyckelord :aktiv aerodynamik; reglerteknik; aktuator; reglersystem; nedåtkraft;

    Sammanfattning : Den här kandidatuppsatsen undersöker möjligheten att konstruera ett system som med hjälp av ett rörligt aerodynamiskt element reglerar den nedåtkraft ett fordon utsätts för vid olika störningar. För att manipulera det aerodynamiska elementet utvecklas en aktuator. LÄS MER

  5. 4. Evaluation of Active Rear Steering through Multi-Body Simulation

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Matteo Rossi; Gabriele Bertoli; [2021]
    Nyckelord :Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Sammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

  7. 5. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Haoran Zhang; [2021]
    Nyckelord :Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

    Sammanfattning : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. LÄS MER
