  1. 1. Environmental Testing of Large Components

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Kenan Güler; Myriam Tenace; [2023]
    Nyckelord :battery packs; large electric components; random vibration; sine sweep; vibration testing.; batteripacken; random vibration; sinus sweep; stora elektriska komponenter; vibrationstestning.;

    Sammanfattning : As the industry is being reshaped concentrically around sustainability, the consumption of fossil fuels is targeted to decrease day by day. As a consequence of that, a righteous rise of electricity as energy source prevails in different branches of industry. LÄS MER

  3. 2. Methodology for analysis of vibration isolating systems

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Jonas Olsson; [2023]
    Nyckelord :Vibration;

    Sammanfattning : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. LÄS MER

  4. 3. Numerisk förutsägelse av markinducerade vibrationer på en byggnad

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Tommaso Meinardi; [2023]
    Nyckelord :;

    Sammanfattning : When a building is constructed close to high-speed traffic infrastructure, the assessmentof the level of vibration in those structures is relevant to guarantee safety and comfort.As long as the number of those buildings is continuously rising, is important to have amethod to evaluate ground-born vibrations that require the lower computational timepossible.

  5. 4. Global Analysis of a Tall Timber- Concrete Hybrid Structure Subjected to Wind Load : A Parametric Study of Different Hybrid Solutions

    Master-uppsats, KTH/Betongbyggnad

    Författare :Clara Youssef; Meriam Basilious; [2022]
    Nyckelord :;

    Sammanfattning :   Tall timber structures have received more attention in recent times as building withtimber contributes to environmental benefits in comparison to other building materials.Timber- concrete hybrid structures have become an alternative as previous investigationshave shown that building tall timber buildings implies complexities with regardsto sufficient stiffness and discomfort for occupants.
