  1. 1. 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

  3. 2. AutoTruck : Automated docking with internal sensors

    Kandidat-uppsats, KTH/Mekatronik

    Författare :OSCAR ANDERSSON; LUCAS MOLIN; [2018]
    Nyckelord :Mechatronics; Trailer; Truck; Articulated vehicle; Self driving; Mekatronik; Trailer; Lastbil; Ledat fordon; Självkörande;

    Sammanfattning : The purpose of this bachelor thesis was to discover how an articulated vehicle can park itself using a pre-defined parking path with a combination of ultrasonic sensors as well as a rotary angle sensor. The project was divided into two parts: constructing a small scale demonstrator and the software controlling the demonstrator. LÄS MER
