  1. 16. Modeling and Concept Design of Wave Energy Device

    University essay from KTH/Marina system

    Author : Rickard Holmgren; [2016]
    Keywords : ;

    Abstract : It has been suggested that it is feasible to extract energy from ocean waves which may be used to generate electricity. This thesis is centered on a wave energy converter system, which is known as a point absorber, which in its most simple design may be seen as a buoy moving up and down due to the wave motions.

  3. 17. Influence of Fluid Structure Interaction on a Concrete Dam during Seismic Excitation : -Parametric analyses of an Arch Dam-Reservoir-Foundation system

    University essay from KTH/Betongbyggnad

    Author : Rikard Hellgren; [2014]
    Keywords : seismic; fluid-structure interaction; arch dam; concrete; finite element analysis; jordbävning; fluid-struktur interaction; valvdamm; betong; finit element analys;

    Abstract : The aim of this study is to investigate how Fluid-Structure interaction is included in numerical earthquake analyses of dams. The base for this project is theme A from the 12th international benchmark workshop on numerical analysis of dams, which was held in October 2013. READ MORE

  4. 18. Simulation, design and experimental validation of a passive magnetic damper for ultra-fast actuators

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Chen Chen; [2014]
    Keywords : Damping; Thomson actuator; eddy currents; magnets; ferromagnetic materials;

    Abstract : A contact system driven by a high energetic Thomson actuator requires to be decelerated from full speed down to zero. The forces originated from the interaction between a stationary copper tube and a moving array of magnets combined with plastic or ferromagnetic material are used to generate eddy-current damping.
