  1. 1. Environmental Testing of Large Components

    University essay from KTH/Skolan för industriell teknik och management (ITM)

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : 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.;

    Abstract : 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. READ MORE

  4. 3. Paper Machine Press Felt Monitoring : A Case Study on PM2 in Karlsborg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Aron Laurell Håkansson; [2021]
    Keywords : paper machine; press fabric; press felt; vibration; condition monitoring; pappersmaskin; pressduk; pressfilt; vibration; tillståndsövervakning;

    Abstract : Press felts are highly critical components of the paper machine. A degraded press felt could lead to paper web breaks, which requires the paper machine to be restarted. Moreover, a degraded felt influences the quality of the paper, leading to paper disposal. READ MORE

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

    University essay from KTH/Betongbyggnad

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

    Abstract : 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. READ MORE

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

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

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

    Abstract : 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. READ MORE
