  1. 1. Modeling of a Hydraulic Rock Drill for Condition Monitoring

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Adam Kagebeck; Mahdi Najafi; [2022]
    Nyckelord :Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

    Sammanfattning : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. LÄS MER

  2. 2. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arun Kumar Thakur; [2022]
    Nyckelord :Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Sammanfattning : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. LÄS MER

  3. 3. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Nyckelord :co-simulation; water hammer; cavitation;

    Sammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

  4. 4. Modeling of Biomass Gasification with Adaptation to Biological Methanation Using Aspen Plus®

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Abdallah Almashharawi; [2022]
    Nyckelord :Biomass gasification; Cyclone gasifier; Aspen Plus; Syngas; Synthesis gas; Biogas; Biological methanation; Methane; CO2; RISE; Meva; Gas-cleaning; Gas cleaning; equilibrium; kinetic; pyrolysis; validation; Moisture content; Chemical engineering; Technology and Engineering;

    Sammanfattning : حظيت البدائل المتجددة باهتمام كبير في ظل انخفاض موارد الوقود الاحفوري المتاحة وزيادة المتطلبات البيئية. ان انتاج المواد الكيميائية والوقود المتجدد من خلال استغلال الكتلة الحيوية يقدم طريقا واعدا لدفع هذا التحول الى الامام. LÄS MER

  5. 5. Material Characterization and Blade Impact Simulation

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

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER
