  1. 1. Bränder i Elektrifierade Truckar

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Cecilia Östholm; [2024]
    Nyckelord :Litium-jon batteri bränder; Elektrifierade truckar; Förebyggande åtgärder; Åtgärder under brand; Litteraturstudie; Intervjustudie.; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

  3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  4. 3. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  5. 4. Design av fysiskt användargränssnitt till ett luftburet skördarverktyg

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Mohamed Mohamud; Kasper Olsson; [2023]
    Nyckelord :drönare; skördaraggregat; användargränssnitt; ergonomi; inmatning; konceptgenerering;

    Sammanfattning : Forest thinning involves the removal of some trees to benefit the other trees in the forest. When forestsare thinned, heavy machines are used that drive through the forest and affect the forest negatively. The company Airforestry is developing a new system that offers the possibility of thinning from the air using an electric drone. LÄS MER

  7. 5. Development of Forklift Protectors : Reducing damages to goods in a warehouse setting

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Lukas Håman; Jonathan Åhstedt; [2023]
    Nyckelord :Forklift; damage; warehouse; protector;

    Sammanfattning : Warehouses are essential for any logistical operation, and Forklifts are efficient tools for moving products and pallets inside warehouses. Forklifts are also heavy machines that are prone to inflict damage on pallets and goods. The demand for forklift operators increases with the demand for forklifts. LÄS MER
