  1. 1. Analysis of Footbridge Comfort Vibrations

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Niklas Thuresson; Henrik Ruuth; [2023]
    Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

    Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE

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

    University essay from KTH/Industriell produktion

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

    Abstract : 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. 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. 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

  6. 5. 3D Printed Lattice Structure for Driveline Applications

    University essay from KTH/Materialvetenskap

    Author : Boyu Xue; [2021]
    Keywords : Lattice structure; AM Additive Manufacturing ; topology optimization; lattice optimization; NVH noise; vibration and harshness ; mechanical performance; lightweight; driveline; natural frequency; Gitterstruktur; AM additiv tillverkning ; topologioptimering; optimering av gitter; NVH buller; vibrationer och obehag ; mekanisk prestanda; lättvikt; drivlina; egenfrekvens;

    Abstract : Lattice structures have received a lot of attention as cellular materials in recent years because of their outstanding properties, such as high strength-to-weight ratio, heat transfer, energy absorption, and capability of improving noise, vibration and harshness (NVH) behavior. This type of structure received a boost from additive manufacturing (AM) technology, which can fabricate geometries in practically any shape. READ MORE
