  1. 11. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

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

    Författare :Diego Manuel Chamorro Ruz; [2022]
    Nyckelord :micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Sammanfattning : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. LÄS MER

  4. 13. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

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

    Författare :Zapata Tamayo Juan Guillermo; [2021]
    Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

  5. 14. Study of Diamond Folds in Mass-Impregnated(MI) Cables

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sucheth Krishna Kumar Bysani; [2021]
    Nyckelord :FEM; MI cable insulation; diamond fold buckling; lapping tension; registration andbutt-gap;

    Sammanfattning : High Voltage (HV) cables are designed to transmit electrical power from the source to the placewhere it is consumed. The global trend towards renewable energy sources e.g. LÄS MER

  7. 15. Kraftvärme - En förbisedd grundpelare i morgondagens förnybara elsystem

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Truls Martinsson; [2021]
    Nyckelord :Combined heat-and-power; ancillary services; inertia; reactive power; optimization; profitability; Technology and Engineering;

    Sammanfattning : The Swedish power system, similar to those of other European countries, is currently transitioning from fossil to renewable. Simultaneously the electrification and digitalization of societies all over the world sets high standards for the availability of power. As a result the power systems experience certain limitations and issues. LÄS MER
