  1. 6. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Malin Strandberg; [2021]
    Nyckelord :Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

    Sammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

  3. 7. Strategies for Road Profile in Adaptive Suspension Control

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Fredrik Skoglund; [2020]
    Nyckelord :;

    Sammanfattning : Semi-active suspension systems has become an increasingly popular alternative to the passive suspensions in recent time. By varying the spring stiffness and damping coefficient in the system, different characteristics can be achieved depending on driver preferability and road disturbances. LÄS MER

  4. 8. Static and dynamic characterization of elastomers by a modified hardness test

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Omar Chouman; [2019]
    Nyckelord :Rubber; elastomer; modified hardness test; dynamic and static characterization; damping; dynamic shear modulus; hyperelastic material; hyperelastic constants; finite element method; FEM; FEA; Abaqus; Volvo Cars; Technology and Engineering;

    Sammanfattning : Today rubber can be found in many different applications, such as vibration dampers, tyres, clothes and gaskets. Two different types of rubbers are used today, namely the natural rubber and synthetic rubber. Natural rubber is made of a milky substance called latex, which is obtained from special trees found in tropical countries. LÄS MER

  5. 9. Numerical and experimental dynamic analyses of the Vega Pedestrian bridge including seasonal effects

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :John Hallak Neilson; [2019]
    Nyckelord :;

    Sammanfattning : As timber structures become increasingly relevant and sought after – since they enable improvements in building time while reducing a structure’s life cycle impacts – streamlining their design can have meaningful economic and environmental implications.For timber footbridges, its design is frequently governed by serviceability criteria linked to excessive vibrations.
