    Sammanfattning : Volvo Cars is in a change of producing only electric and hybrid cars by 2025.Subcomponent testing is a crucial part to ensure the quality of the individual buildingblocks in an electric machine. Any way of making these tests more reliable and less timeconsuming is of great interest at Volvo. LÄS MER

  3. 12. 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

  5. 14. Hybrid Vehicle Control Benchmark

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Ruchit Anilbhai Bhikadiya; [2020]
    Nyckelord :Hybrid electric vehicle; Dynamic Programming; Powertrain Modes;

    Sammanfattning : The new emission regulations for new trucks was made to decrease the CO2 emissions by 30% from 2020 to 2030. One of the solutions is hybridizing the truck powertrain with 48V or 600V that can recover brake energy with electrical machines and batteries. The control of this hybrid powertrain is key to increase fuel efficiency. LÄS MER

  7. 15. Virtual testing of self-piercing rivet connections

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

    Författare :Daniel Andersson; Fredrik Saliba; [2020]
    Nyckelord :FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

    Sammanfattning : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). LÄS MER
