  1. 1. Statistical Analysis and Modelling of Engine Oil Degradation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nils Bastiampillai; [2023]
    Nyckelord :;

    Sammanfattning : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.

  3. 2. Utvärdering av V2G : Lönsamhet och miljöpåverkan med N(D)-baserad degraderingsmodell för elbilsbatterier

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Sjögren Johan; [2023]
    Nyckelord :V2G; batteri; batteridegradering; N D ; energi;

    Sammanfattning : The transition from combustion engine vehicles to electric vehicles (EV) is an important step in achieving a carbon neutral society, but poses future difficulties in energy production. This is an issue in sustaining sufficient net energy, as well as providing sufficient power during hours of high demand. LÄS MER

  4. 3. Modelling the Occurrence and Fate of Microplastics Caused by Tyre Wear on Highway E18

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Aniruddha Kshirsagar; [2023]
    Nyckelord :Tyre Wear Plastics; stormwater system; Microplastics; settling; hetero-aggregation; modelling; Modellering; mikroplaster;

    Sammanfattning : The accumulation of microplastics (MPs) are a growing concern for the environment, the maximum contributor to the MP pollution is tyre wear particles or TWPs. TWPs can accumulate in the environment and remain there for long periods of time and hence have the ability to disrupt ecosystems. LÄS MER

  5. 4. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Rabia Arshad; [2022]
    Nyckelord :Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Sammanfattning : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. LÄS MER

  7. 5. Pantograph-catenary wear modelling using dynamic simulation

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Gaston Holmström; [2022]
    Nyckelord :Wear modelling; catenary pantograph interaction; mechanism; conditional; railway; slitagemodellering; kontaktledning pantograf interaktion; mekanism; konditionell; järnväg;

    Sammanfattning : Wear condition modelling is a research topic which lately has increased in popularitydue to its significance to the railway industry. Large sums are spent on maintenanceof the network every year, which has generated a demand for understanding and predictingwear mechanisms in a multitude of components within both railway vehiclesand infrastructure.
