  3. 3. Electrohydraulic Power Steering Simulation : Dynamic, thermal and hydraulic modelling

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oskar Svensson; [2019]
    Nyckelord :PMSM; SVPWM; vector control; FOC; lumped parameter model; LPM; hydraulic pump; simulation;

    Sammanfattning : There are several benets of electrohydraulic power steering systems, as compared to hydraulicpower steering systems where the pump is driven directly by the engine of the vehicle. Someof these benets are increased eciency and improved steering performance. LÄS MER

  4. 4. Evaluation of a digitial displacement pump in a load haul dump application

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Jayasurya Madhusudanan; [2019]
    Nyckelord :Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

    Sammanfattning : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. LÄS MER

  5. 5. Högupplöst varvtalsgivare till hydraulisk radialkolvmotor

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik
