  1. 1. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

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

    Författare :Anton Sundström; [2020]
    Nyckelord :DEM; Discrete element method;

    Sammanfattning : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. LÄS MER

  2. 2. Improving comfort simulations of sleeping mattresses for IKEA

    Master-uppsats, Lunds universitet/Produktutveckling

    Författare :Joel Elinder; [2020]
    Nyckelord :LS-Dyna; explicit finite element simulations; compressive testing; human soft tissue material models; mass scaling; hyperelastic material model validation; material validation; explicit timestep; Technology and Engineering;

    Sammanfattning : It is beneficial for a furniture company like IKEA to objectively and accurately evaluate what makes a mattress comfortable. But what defines comfort? IKEA currently investigates mattress comfort through extensive real-life user testing. Through which, six parameters of comfort have been identified. LÄS MER

  3. 3. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

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

    Författare :Jamal Choudhry; [2020]
    Nyckelord :DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

    Sammanfattning : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. LÄS MER

  4. 4. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Sohail Anwar; [2020]
    Nyckelord :Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Sammanfattning : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). LÄS MER

  5. 5. Influence of Active Musculature & Parameters of the Final Pre-Crash State on the Occupant Response

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lara Wehrmeyer; [2020]
    Nyckelord :Human body model; active musculature; occupant parameters; frontal impact; pre-crash manoeuvre; LS-Dyna; Aktiva humanmodell; aktiva muskler; åkande respons; frontal kollision; pre-crash manöver; LS-Dyna;

    Sammanfattning : Collision avoidance systems have become an integrated part of modern vehicles and aim to avoid accidents or mitigate the crash severity for the occupant. For example, the autonomous emergency braking system influences the pre-crash state of the occupant in sitting posture, stress state, or velocity. LÄS MER
