  1. 1. Electric Leisure Boats: Enablers and Barriers : A case study of leisure boat manufacturers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FREDRIK IHRFELT; [2023]
    Nyckelord :Leisure boats; electric boats; electrification; technology management; innovation; industrial transformation; accelerators.; Fritidsbåtar; elbåtar; elektrificering; teknikledning; innovation; industriell transformation; påskyndare.;

    Sammanfattning : Combustion engines and fossil fuels have traditionally driven motor-powered leisure boats. Electrification is quickly transforming the transportation sector, but electric boats are rare. The primary drawback of the electric boat is the high production cost. LÄS MER

  3. 2. Implementering av datadriven digital tvilling för förbättrande underhåll på ett torkcylindersystem

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Parwand Batti; [2023]
    Nyckelord :Datadriven; digital tvilling; IoT; ThingSpeak; torkcylinder; underhåll; MATLAB; C#;

    Sammanfattning : A digital twin is a digital representation of a real-world physical object (a physical twin), and useful for product lifecycle management and maintenance. The aim of this project is to implement a data-driven digital twin for a system consisting of an electric motor, a gearbox and a drying cylinder, in order to improve the maintenance plan and reduce maintenance costs for a drying cylinder system.

  4. 3. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Johan Humla; Samuel Friman; [2023]
    Nyckelord :;

    Sammanfattning : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. LÄS MER

  5. 4. Alternative traction system for road-rail vehicles

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jakob Runevad; [2023]
    Nyckelord :Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Sammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER
