  1. 1. Comparison of finite element modelling techniques applied on Gripen structure

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mathias Goodhe; [2023]
    Nyckelord :Finite element method; FEM; Global FEM; Detailed FEM;

    Sammanfattning : The goal of the thesis was to investigate and compare internal loads and bolt loads from different modelling methods using finite element method, from global to detailed, applied to a topologically correct air brake of a JAS 39 Gripen. The finite element method is a common used method for analysing strength properties of different structures. LÄS MER

  2. 2. Reduced stress method for steel in class 4 cross-sections : Evaluation of the reduced stress method for a railway bridge

    M1-uppsats, KTH/Byggteknik och design

    Författare :Therese Badrous; Ebba Lund; [2021]
    Nyckelord :FEM; Reduced stress method; Effective cross-section method; Local buckling; Steel cross-section; Class 4 cross-section; Railway bridge; FEM; Reducerad spänningsmetoden; Effektivt tvärsnittsmetoden; Lokal buckling; Ståltvärsnitt; Tvärsnittklass 4; Järnvägsbro;

    Sammanfattning : The effective cross-section method, also called reduced cross-section method is generally used for steel in class 4 cross-sections in considering local buckling. This method is a bit complicated and time consuming, which often leads to engineers not using profiles in class 4 cross-sections. LÄS MER

  3. 3. Vibrational prediction of a waste water pump

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Daniel Sundström; [2020]
    Nyckelord :;

    Sammanfattning : An off-market waste water pump is suspected to have high vibrational velocity levels. These vibrations are sought after at the outer surface located at the upper bearing position of the pump. It has then become of interest for trying to predict these vibrations by using the commercial FEA software COMSOL. LÄS MER

  4. 4. Skruvmönster för samverkansbjälklag bestående av LVL och I-balk

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Charlie Nordlinder; [2019]
    Nyckelord :Provningar; Samverkansbjälklag;

    Sammanfattning : Masonite Beams is a company that produces I-beams. They are also working on developing a building system for industrial production of building components. A part of their building system is a composite floor, consisting of LVL and I-beams. LÄS MER

  5. 5. Breddning av samverkansbroar : En studie om förberedande åtgärder vid nyproduktion av samverkansbroar för att klara framtida körfältsökningar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jacob Fredriksson; [2019]
    Nyckelord :Composite action; bridge; widening; concrete; steel; samverkan; bro; breddning; betong; stål;

    Sammanfattning : The purpose of this master thesis is to provide suggestions of how composite bridges with I-beams (steel beams and concrete slab connected via shear connectors) can be prepared during the construction phase to withstand a future widening. As a case study the project "Bridge over Kalix river in Kalix" has been used. LÄS MER
