  1. 6. Development of Spring Wire Feeder : Design for Spring Manufacturing with Coarse Spring Wire

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Martin Similä; [2021]
    Nyckelord :product development; product development process; Rejlers; produktutveckling; produktutvecklingsprocess; Rejlers;

    Sammanfattning : Lesjöfors Fjädrar AB is a spring manufacturing company. At the start of each manufacturing process when manufacturing cold coiled compression springs, the operators manually feed the spring wire from a reel that contains the raw spring wire, into the machine where the springs are made. This is a demanding process for the operators. LÄS MER

  3. 7. Energy Consumption Optimization of Electric Vehicles

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Zhifeng Sun; [2021]
    Nyckelord :Electric vehicle; torque allocation; regenerative braking; LQR; rear axle steering; Elfordon; tilldelning av vridmoment; regenerativa bromsstrategier; LQR; bakaxelstyrning;

    Sammanfattning : This master thesis report has studied several methods to improve the energy consumption of an electric vehicle equipped with two permanent magnet synchronous motors. Two driving torque distribution maps are developed based on efficiency map and load transfer, respectively. The drive torque distribution map based on the efficiency map shows up to 8. LÄS MER

  4. 8. 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

  5. 9. Steering system development using test rig and driving simulators

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Utsav Khan; Andrea Bianchi; [2019]
    Nyckelord :;

    Sammanfattning : Conventional model-based development approaches such as Model-in-Loop (MiL) and Software-in-Loop (SiL) have been used in electric power assisted steering (EPAS) development in recent years, but when it involves a physical motor and the vehicle communication network, the development mostly comes down to real vehicle testing and tuning. The objective and outcome of this master thesis is to develop a Hardware-in-Loop (HiL) environment that involves the real EPAS powerpack and human Driver-in-Loop (DiL) using a static driving simulator.

  7. 10. Ångdrift av värmepump på Sysavs förbränningsanläggning

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Johanna Anderberg; [2018]
    Nyckelord :chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : På Sysavs förbränningsanläggning sker en samproduktion av el och värme där Sysav har tillstånd att förbränna 630 000 ton avfall. Föregående år producerades totalt 265 530 MWh el och 1 501 150 MWh värme från förbränningen. LÄS MER
