  1. 1. Improved methodology for postulated fuel handling accident

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Max Fagerberg; [2020]
    Keywords : ANSYS LS-DYNA; FEM; nuclear fuel; solid mechanics; Technology and Engineering;

    Abstract : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. READ MORE

  3. 2. Response of Footbridges equipped with TLD : A numerical and experimental assessment

    University essay from KTH/Bro- och stålbyggnad

    Author : Silhady Tshitende Luboya; [2020]
    Keywords : Tuned liquid damper; tuned mass damper; dynamic analysis; dynamics evaluation; vibration; footbridge; human-induced vibrations; parametric study; serviceability; assessment.;

    Abstract : In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. READ MORE

  4. 3. Numerical Calculations of Wireless Power Transfer Coil Parameters

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Jonatan Nyström; [2020]
    Keywords : WPT; Wireless; Charging; Qi; Inductance; Calculation; Inductive; Coupling; Technology and Engineering;

    Abstract : Wireless Power Transfer (WPT) has become a commercially viable technology. The technology uses the phenomenon of electromagnetic induction between coils to transfer electrical power wirelessly. READ MORE

  5. 4. Numerical analysis of aerodynamic damping in a transonic compressor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vincenzo Stasolla; [2019]
    Keywords : transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.
