  1. 1. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation

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

    Författare :André Wirthig; [2023]
    Nyckelord :Vibrations; High frequency floors; Sensitive equipment; Technology and Engineering;

    Sammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER

  3. 2. 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.

  4. 3. Predicting Location-Dependent Structural Dynamics Using Machine Learning

    Master-uppsats, KTH/Industriell produktion

    Författare :Markus Zink; [2022]
    Nyckelord :machine learning; artificial intelligence; gradient boosting; LightGBM; multilayer perceptron; prediction; chatter; vibration; structural dynamics; modal parameters; machine tool; tool centre point; work envelope;

    Sammanfattning : Machining chatter is an undesirable phenomenon of material removal processes and hardly to control or avoid. Its occurrence and extent essentially depend onthe kinematic, which alters with the position of the Tool Centre Point, of the machine tool. LÄS MER

  5. 4. Space Rider System: GNC and System Model Improvements

    Master-uppsats, KTH/Rymdteknik

    Författare :Simon Vial; [2022]
    Nyckelord :Space Rider System; Disturbance Modelling; Maneuver Optimization; Space Rider System; Modellering av Störningar; Manöveroptimering;

    Sammanfattning : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. LÄS MER

  7. 5. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Persson; [2022]
    Nyckelord :Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Sammanfattning : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. LÄS MER
