  1. 6. Analysis of a Plate of High Strength Steel: Simulation of Impact and Determination of Residual Stresses

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Martin Hviid; [2021]
    Nyckelord :;

    Sammanfattning : In this study a finite element model has been created in ABAQUS/Standard in order to replicate impact tests performed by SSAB and to determine residual stresses in a plate. Uniaxial tensile tests have been done in order to determine the plastic behaviour of a high strength steel from the manufacturer SSAB and to determine whether the material can be assumed to be isotropic.

  3. 7. Simulation of Rolling Mill to Computeand Improve Load Distribution

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

    Författare :Pontus Darth; [2021]
    Nyckelord :Finite Element; Simulation; Hot rolling mill; SSAB; Swerim AB; Roll Spallings; Spallings; Roll Failure;

    Sammanfattning : This master thesis was done at Swerim AB in cooperation with SSAB and the Technical University of Luleå in the purpose of preventing spalling problems in hot rolling mills. Spallings are a fatigue damage that occurs on the rolls due to extreme loads and unfavorable conditions between the rolls in a mill. LÄS MER

  4. 8. FE-Modelling of a Joint for Cross-Laminated Timber

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Linus Ekhagen; [2021]
    Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER

  5. 9. Development of Advanced Process Control for Controlling a Digital Twin as a Part of Virtual Commissioning

    Master-uppsats, Högskolan i Gävle/Elektronik

    Författare :Md Mehrab Uddin; [2021]
    Nyckelord :Virtual Commissioning; Digital twin; System modeling; Control system; Rolling mill; Industrial control system; PLC; HMI; OPC UA; STEP 7 TIA portal; PLCSIM Advanced; Model-in-the-loop; MIL; Software-in-the-loop; SIL;

    Sammanfattning : Over the last few decades, the complexity and variety of automation systems have increased dramatically. Commissioning has grown more and more critical for the entire industry. Conventional commissioning is time-consuming and expensive. LÄS MER

  7. 10. Monitoring energy efficiency of heavy haul freight trains with energy meter data

    Master-uppsats, KTH/Spårfordon

    Författare :Philipp Geiberger; [2021]
    Nyckelord :Energy consumption; Energy meter; Energy monitoring; Heavy haul freight train; Key performance indicator; Multi-particle model; Simulation; Energiförbrukning; Elmätare; Energiuppföljning; Tungt godståg; Nyckeltal; Flerpartikelmodell; Simulering;

    Sammanfattning : In this MSc thesis, it is investigated what parameters are relevant for describing energy consumption of heavy haul freight trains and how these can be used to develop key performance indicators (KPIs) for energy efficiency. The possible set of KPI is bounded by data available from energy meters used in electric IORE class locomotives hauling iron ore trains in northern Sweden. LÄS MER
