  1. 1. Steering system modal analysis

    Master-uppsats, KTH/Teknisk akustik

    Författare :Silvia Milani; [2023]
    Nyckelord :Ride comfort; Steering wheel vibrations; Resonance excitations; Åkkomfort; Rattvibrationer; Resonansexcitationer;

    Sammanfattning : The vehicle manufacturing sector is constantly evolving, and corporations are fully aware of increased consumer expectations for both driver and passenger´s comfort. SCANIA CV AB, as one of the largest Swedish manufacturers of commercial vehicles, has put an emphasis on this area. LÄS MER

  3. 2. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    Master-uppsats, KTH/Teknisk akustik

    Författare :Oscar Lundin; [2022]
    Nyckelord :Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Sammanfattning : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. LÄS MER

  4. 3. Massdämpning av vridmoment i stenkross

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Ekman Dennis; Veronika Nerbe; [2021]
    Nyckelord :;

    Sammanfattning : Sandviks stenkrossar brukas i ett flertal industrier där dess syfte är att minska storleken på inmatad sten. Ett konstaterat problem för maskinen i fråga är förslitningar som till slut resulterar i utmattning. LÄS MER

  5. 4. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

    Master-uppsats, KTH/Betongbyggnad

    Författare :Stella Harrison; Siri Nöjd; [2021]
    Nyckelord :concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

    Sammanfattning : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. LÄS MER

  7. 5. Operational modal analysis and finite element modeling of a low-rise timber building

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Viktor Petersson; Andreas Svanberg; [2021]
    Nyckelord :Timber structure; Dynamic behavior; Operational modal analysis; FE-modeling; Mode shape; Natural frequency.; Träbyggnad; Dynamiskt beteende; Operational modal analysis; FE-modellering; Egenmod; Egenfrekvens.;

    Sammanfattning : Timber is a building material that is becoming more common and of interest for use in high-rise buildings. One of the reasons is that timber requires less energy input for the manufacturing process of the material compared to non-wood based materials. LÄS MER
