  1. 1. Bedömning av enskilda trafikimmissioners marknadsvärdepåverkan på småhus vid anläggning, omläggning och breddning av väg.

    Master-uppsats, Lunds universitet/Fastighetsvetenskap

    Författare :Elenie Beyene; [2023]
    Nyckelord :Environmental damage; market reduction; property value; property valuation; assessment. Miljöskada; företagsskada; marknadsvärdeminskning; fastighetsvärdering; bedömning.; Technology and Engineering; Law and Political Science;

    Sammanfattning : During the construction, realignment, or widening of roads, various disturbances can occur that affect the market value of nearby properties. These disturbances typically include things such as increased noise, vibration, changes in soil conditions, increased sensitivity to wind, and all contibute to severe disruption of the property.

  3. 2. Viktreducering av monteringsfixtur genom simulering

    M1-uppsats,

    Författare :Sebastian Cronring; Jacob Olai; [2023]
    Nyckelord :Topology optimization; Design of Experiments; Finite element analysis; Dynamic analysis; simulation-based work; Iterative process; Topologioptimering; Design of Eperiments; Finita element analys; Dynamisk analys; Simulerings baserat arbete; Iterativ design.;

    Sammanfattning : At Saab Training & Simulation, there are set strength requirements in the form of quality testing for its products through vibration testing. This is done to ensure the quality of the products, but the vibration machine can only test products up to a set weight limit. 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. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

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

    Författare :Johannes Jonasson; Olle Karlsson; [2022]
    Nyckelord :hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

    Sammanfattning : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. LÄS MER

  7. 5. Numerical study of a vibroacoustic wave trap for e-vehicles

    Master-uppsats, KTH/Teknisk akustik

    Författare :Antoine Curien; [2022]
    Nyckelord :wheel vibrations; passive vibration control; multiple tuned mass damper; bending mode; numerical optimisation; damping; resonance; robustness; reduction methods; Hjulvibrationer; passiv vibrationsreglering; multi tuned mass damper; böjningsläge; numerisk optimering; dämpning; resonans; robusthet; modale reduktionsmetoder;

    Sammanfattning : The transition from internal combustion engine to battery electric cars is accompanied by a shift on the NVH issues damaging the passenger comfort. The rolling noise generated by the wheels and tyres is in particular characterized by an increasing attention from OEMs and car manufacturers. LÄS MER
