  1. 16. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  3. 17. Modelling of a high-performance vehicle in MATLAB/Simulink and Canopy Simulations

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Rickard Höglund; [2022]
    Keywords : Vehicle Engineering; vehicle development; modelling; simulation; longitudinal model; lateral model; standard maneuver; Fordonsteknik; fordonsutveckling; modellering; simulering; longitudinell modell; lateral modell; standardmanöver;

    Abstract : The car industry is constantly evolving. High demands from customers and governing bodies force the manufacturers to speed up development of new vehicle models. This process used to be a very costly, time consuming and not very ecologically sustainable because new and expensive parts had to be made that are difficult to manufacture. READ MORE

  4. 18. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Emil Vejlens; Dylan De Jourday; [2022]
    Keywords : Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

    Abstract : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. READ MORE

  5. 19. Simulation of Transformer Inrush Currents and Their Impact on the Grid

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Juan de la Peña Toledo; [2022]
    Keywords : Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

    Abstract : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. READ MORE

  6. 20. Evaluation of Active Rear Steering through Multi-Body Simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Matteo Rossi; Gabriele Bertoli; [2021]
    Keywords : Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Abstract : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.
