  1. 1. Small-scale wave energy converter for wave tank facility

    University essay from Uppsala universitet/Elektricitetslära

    Author : Samir Asseh; [2023]
    Keywords : Wave power; small-scale; Wave tank; facility; Renewable resources; damping; froude scaling; magnets; copper coil; Uppsala University; buoy; MATLAB; COMSOL; PTO; WEC; Electricicity generation.; Förnybar energi; Vågtank; Vågkraft;

    Abstract : A small-scale wave energy converter was designed and built for teaching and academic purposes to be used at The Division for Electricity, in the Ångström Laboratory at Uppsala University. The design of the power take-off (PTO) makes use of magnets passing through a copper coil for electricity generation. READ MORE

  2. 2. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

  3. 3. Design of a small-scale wave energy converter

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sumaya Farjana; [2022]
    Keywords : small-scale point absorber; scaling factors; damping coefficient;

    Abstract : In this study, a small-scale point absorber wave energy converter has been designed contemplating a full-scaled point absorber in the Mediterranean Sea state. The scaling factor for the small-scaled version has been determined by the damping coefficient calculation of the power take-off in 1:10, 1:15, and 1:20 scaling factors. READ MORE

  4. 4. Dynamic Simulation and Suspension Optimization for a Heavy Duty Railway Bogie

    University essay from KTH/Spårfordon

    Author : David Prifer; [2021]
    Keywords : Rail vehicle; Bogie Technology; Running Dynamics; Simulation; Simpack; Vehicle Acceptance; Validation; Järnväg; Gångegenskaper; Flerkroppssimulering; Acceptanskrav;

    Abstract : A multi-body simulation study was undertaken to investigate the running behavior of a rail grinder vehicle with newly developed Ganz bogies. The main purpose of the simulations was to forecast and support the vehicle acceptance tests and support the ongoing development. READ MORE

  5. 5. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Jacob Wallersköld; Johan Appelros; [2021]
    Keywords : wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

    Abstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE
