  1. 1. Aerodynamic Design in Axial Turbine for Heavy Duty Applications

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Eric Lennman; [2020]
    Nyckelord :Turbine design; MULTALL; Design methodology; Electric turbo compound turbine; Technology and Engineering;

    Sammanfattning : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. LÄS MER

  2. 2. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

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

    Författare :Jamal Choudhry; [2020]
    Nyckelord :DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

    Sammanfattning : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. LÄS MER

  4. 4. Dynamic prediction of repair costs in heavy-duty trucks

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Lakshidaa Saigiridharan; [2020]
    Nyckelord :Hurdle Gamma model; Hierarchical hurdle Gamma model; Generalized linear model GLM ; Supervised Machine Learning; feature selection; Akaike Information Criterion AIC ; prediction of repair costs; heavy-duty trucks; truck variants; operational features;

    Sammanfattning : Pricing of repair and maintenance (R&M) contracts is one among the most important processes carried out at Scania. Predictions of repair costs at Scania are carried out using experience-based prediction methods which do not involve statistical methods for the computation of average repair costs for contracts terminated in the recent past.

  5. 5. Alternative Drivetrain for Future Freight Trucks

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Athanasios Tsamos; [2020]
    Nyckelord :future freight trucks; transportation; sustainable fuels; alternative fuels; future mobility; long distance trucks; hybrid mobility; alternative drivetrain; electric trucks;

    Sammanfattning : Presently, heavy-duty trucks are responsible for approximately 25% of global CO2 emissions. Although the world seems to incline towards the transport sector's electrification, the electrification of long-range freight trucks is profoundly challenging. LÄS MER
