  1. 11. Ultra-light weight design through additive manufacturing

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Barrett Sauter; [2019]
    Nyckelord :additive manufacturing; AM; fused deposition modeling; FDM; polymer; buckling; post-processing treatments;

    Sammanfattning : ABB Corporate Research was looking to redevelop one product to be manufactured via polymer additive manufacturing (AM), as opposed to its previously traditionally manufacturing method. The current product is cylindrical in shape and must withstand a certain amount of hydrostatic pressure. LÄS MER

  3. 12. Modeling and control of a suspended load lifted by two aerial vehicles

    Master-uppsats, KTH/Reglerteknik

    Författare :Massimiliano Pandolfo; [2017]
    Nyckelord :;

    Sammanfattning : In this thesis we discuss the problem of lifting and stabilizing a bar-shaped slungload, held by two UAVs (Unmanned Aerial Vehicles) which are connected to it throughcables. A mathematical model of the system is presented. After describing the systemdynamics, we identify a set of equilibrium poses and discuss the stability of a point inthis set. LÄS MER

  4. 13. EVALUATING THE ORGANIC RANKINE CYCLE (ORC) FOR HEAT TO POWER : Feasibility and parameter identification of the ORC cycle at different working fluid with district waste heat as a main source.

    M1-uppsats, Mälardalens högskola/Framtidens energi

    Författare :Salman Mohamad; [2017]
    Nyckelord :Organic Rankine cycle; Recuporator; regenerative; heat-to power; working fluids; low temperature heat; power generation;

    Sammanfattning : New technologies to converting heat into usable energy are constantly being developed for renewable use. This means that more interactions between different energy grid will be applied, such as utilizing low thermal waste heat to convert its energy to electricity. LÄS MER

  5. 14. En kvalitativ studie om bar modeling som matematisk strategi

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Avdelningen för ämnesdidaktik och matematik

    Författare :Niklas Nygren; [2017]
    Nyckelord :Bar modeling; Singapore math; problemlösning; matematik; matematiska strategier;

    Sammanfattning : Denna studie handlar om den matematiska strategin bar modeling som är tagen från undervisingen i Singapores skolor. Syftet med studien är undersöka om bar modeling fungerar som matematisk strategi och hur eleverna upplever arbetssättet. Utöver att studera metoden i praktiken studeras också hur lärarna uppfattar bar modeling. LÄS MER

  7. 15. Offset modeling of shell elements : A study in shell element modeling using Nastran

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :David Klarholm; [2016]
    Nyckelord :Offset shell elements; finite element; Nastran; shell element modeling; Rigid body connection; Rigid links; Kirchhoff shells; Multipoint constraint;

    Sammanfattning : At Saab Aerostructures they are manufacturing a lot of parts for Airbus and Boeing. When these components are investigated using finite element analysis four-node Kirchhoff shell elements and a very fine mesh is often used. LÄS MER
