  1. 1. Design av en hydraulisk bandspännare

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

    Författare :Nils Forsman; [2023]
    Nyckelord :skogsmaskinsband; skogsmaskin; hydraulik;

    Sammanfattning : Olofsfors AB tillverkar bland annat boggiband för skogsmaskiner. Dessa band kräver en extern spännare vid montering som i dagsläget finns i manuellt och skruvdragardrivet utförande. LÄS MER

  3. 2. Design and evaluation of a shock load resistant dynamic chain plate

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

    Författare :Daniel Olsson; [2022]
    Nyckelord :Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Sammanfattning : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. LÄS MER

  4. 3. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Omar Orgeira Alvarez; [2022]
    Nyckelord :Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

    Sammanfattning : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. LÄS MER

  5. 4. Analysis of Head Kinematics in Ice Hockey

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

    Författare :David Pogosian; [2022]
    Nyckelord :Ice hockey; Video analysis; MPS; THUMS; Concussion; Head kinematics; Finite Element analysis; Ishockey; Videoanalys; MPS; THUMS; Hjärnskakning; Huvudkinematik; Finita element metoden;

    Sammanfattning : Ice hockey has been identified as a sport with a high risk for concussions due to it being highly physical. Improvements have been made over the years to improve the protective gear for the players effectively eliminating more severe traumatic brain injuries (TBIs) however mild concussions (mTBI) are still prevalent to this day.

  7. 5. Simulation of Mechanical Shock with Finite Element Analysis and Estimation of Shock Attenuation

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Cheng Qian; [2021]
    Nyckelord :shock; SRS; FEA; attenuation; chock; SRS; FEA; chockdämpning;

    Sammanfattning : Space equipment is often subjected to mechanical shocks. Some devices like electronics are sensitive to shocks, and they can easily be damaged. To protect these devices, it is important to study shock penetrations in space structures. The Finite Element Method is an effective tool to simulate response to transient excitations. LÄS MER
