  1. 1. Simulations of a self-stabilizing fully submerged hydrofoil

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Henry Jacobson; [2023]
    Nyckelord :Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

    Sammanfattning : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. LÄS MER

  3. 2. Automation of yarnpick : Evaluating a cobots effectiveness for pick and place operations in a textile industry

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

    Författare :Adam Hallin; [2023]
    Nyckelord :Cobot; Automation; Textile; industry; Ergonomics; Simulations; Automatisering; Textil; Industri; Ergonomi; Simuleringar;

    Sammanfattning : Repetitive, strenuous and heavy lifting are working conditions many companies have a hard time to eliminate. Such is the case for the textile company, AB Ludvig Svensson. A big part of the production at the factory is unpacking, loading, unloading and just moving lots of rolls of yarn daily. LÄS MER

  4. 3. Utveckling av lyftverktyg vid monteringen av statorer i elektriska motorer

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Martin Svensson; Axel Himreus; [2023]
    Nyckelord :product development; manufacturing; lifting tools; electrical motors; stator; ergonomics.;

    Sammanfattning : The main purpose of this thesis is to develop an efficient and safe lifting device that can make the manufacturing process of electrical motors efficient but also make the work environment safer. The process of the product development has been following steps taught at Universities around the world. LÄS MER

  5. 4. Development of Unloading Station by Concept Generation and Ergonomic Evaluation

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

    Författare :Alex Kauppi; [2022]
    Nyckelord :Product development; Scania; Ergonomics in production; SES RAMP; Workers collective; Lean;

    Sammanfattning : This thesis presents a product development project done at Scania Ferruform in Luleå. The process that was used is called Stage-Gating which means that the project is divided into gates. LÄS MER

  7. 5. Realizing a screwdriving operation for human-robot collaboration : During the assembly of a truck engine valve-hood

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Arturo Mateos Rodríguez; [2021]
    Nyckelord :;

    Sammanfattning : According to Folgiatto, da Silveira and Borenstein (2012), the current trend in the industry indicates a change from a mass production to a mass customization manufacturing. This mass customization means an increase on the need of flexibility, as the production line must be ready for frequent changes in order to adapt for producing different product variants. LÄS MER
