  1. 1. Structural Analysis and Redesign of a L90 Front Axle Casing

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Erik Berra Widén; [2023]
    Nyckelord :FEM; Ansys Mechanical; Axle Casing; Volvo CE; Wheel Loader; Redesign;

    Sammanfattning : This thesis was commissioned by Volvo Construction Equipment (Volvo CE) to redesign the front axle casing of their L90 wheel loader to be more in line with their larger wheel loaders. The current L90 front axle casing consists of two parts bolted together in the middle. LÄS MER

  3. 2. EXTRACTING REGIONS OF INTEREST AND DETECTING OUTLIERS FROM IMAGE DATA

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Jessica Ström; Erik Backhans; [2023]
    Nyckelord :Artificial Intelligence AI ; Machine Vision; Outlier Detection; Autoencoders; Neural Networks; Region Of Interest ROI ;

    Sammanfattning : Volvo Construction Equipment (CE) are facing the challenge of vibrations in their wheel loaders that generate disruptive noise and impact the driver's experience. These vibrations have been linked to the contact surface between the crown wheel and pinion gear in the vehicles drive-axles. LÄS MER

  4. 3. Operation and Area Restriction of Autonomous Wheel Loaders Using Colour Markings

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Jonathan Fernkvist; Inas Hamzic; [2023]
    Nyckelord :Colour markings; Histogram; Line-following; Machine vision; Mapping; Wheel loader;

    Sammanfattning : This thesis aims to create a system using colour markings for Volvo’s autonomous wheel loaders which determines their restricted area and operation using sensors available on the machine. The wheel loader shall be able to interpret and distinguish different colours of spray paint, and depending on the colour, act accordingly. LÄS MER
