  1. 1. Omkonstruktion av bockverktyg : Från hydraulisk till elektrisk drivning

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Johannes Skarin; Anders Nygren; [2021]
    Nyckelord :actuator; battery; bending; cad; ctc; copper; finite-element; transformer; bockning; batteri; cad; ctc; finita-elementmetoden; koppar; ställdon; transformator;

    Sammanfattning : A hydraulic bending tool is used in the manufacturing of transformer windings at Hitachi ABB Power Grids. This tool is used to create a pitch between the turns in the winding, a process which demands very strict tolerances during bending. Hitachi/ABB believes that the current tool is quite inconvenient and, in some cases, dangerous to use. LÄS MER

  3. 2. Steering of the second front axle in Volvo trucks

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Martin Asplund; Robin Landin; [2020]
    Nyckelord :Vehicles; Volvo; AFRY; trucks; steering; structural analysis; Solidworks; Matlab; safety; environmental; material; Fordon; Volvo; AFRY; lastbilar; styrning; hållfasthet; Solidworks; matlab; lastvagnar; miljö; material; säkerhet;

    Sammanfattning : Every few years, modern heavy-duty vehicles get redesigned and can carry more cargo than previously known. Increasing the amount of cargo means increasing the weight, which then leads to more pressure on the engineers to design improved vehicle frames and axles to distribute this load. A recent addition is a second front axle. LÄS MER

  4. 3. Predicting drag losses & oil flow characteristics in a wet clutch system using numerical analysis

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

    Nyckelord :Master s thesis;

    Sammanfattning : This report presents the Master Thesis done by two students at the Mechanical Engineering program, Design Engineering at Luleå University of Technology. The thesis was performed at Luleå University of Technology in collaboration with BorgWarner PDS located in Landskrona. LÄS MER

  5. 4. Position Control of an Electro-Hydraulic Servo-Valve : IDENTIFICATION, MODELLING, CONTROLAND IMPLEMENTATION

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Johan Nilsson; [2016]
    Nyckelord :;

    Sammanfattning : Hydraulic drives, systems that use pressurized fluids as transmis-sion medium, have a wide range of applications are widespread in to-day’s industry. Like many other systems, hydraulic drives can get dra-matically improved performance by an appropriately designed feedback controller. LÄS MER

  7. 5. Modelling and Control of an Electro-Hydraulic Forklift

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Henrik Bäckman; Anders Brändström; [2016]
    Nyckelord :Modelling; Control; Forklift; MPC; PID; Simulink; SEDC;

    Sammanfattning : To meet the increasing demand on control precision in industrial forklifts, physical modelling of the lifting system has been combined with parameter estimations from data. A number of different controllers have been evaluated in terms of their ability to achieve a load independent lifting speed. LÄS MER
