  1. 1. Slagkraft och tryckkraft från friktionsbaserat hängande conveyor-system

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Ida Johnsson; Oliwer Larsson; [2023]
    Nyckelord :Conveyor-system; Slagkraft; Tryckkraft;

    Sammanfattning : Mål: En rapport har utförts för att undersöka om vad den aktuella slagkraften samt tryckkraft är från OCS två overhead conveyor-system, OCS 150 och OCS 500. Slagkraften uppmättes för att kartlägga en av de krafter som genereras från systemets olika kombinationer av fjädrar, vikt och hastighet. LÄS MER

  3. 2. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

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

    Författare :Kun Feng; [2023]
    Nyckelord :ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

    Sammanfattning : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. LÄS MER

  4. 3. Development of Test Methodologies and Setups for Thrust Measurements of Cold Gas Micro-thrusters for CubeSats

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Aleksander Kipiela; [2022]
    Nyckelord :Thrust measurements; cold gas propulsion; micro thrusters; hanging pendulum; CubeSat; Dragkraftsmätning; kallgasframdrivning; mikrodysor; hängande pendel; CubeSat;

    Sammanfattning : Measuring the thrust of cold gas micro-thrusters, due to the small magnitude of the generated force, is a challenging task, and to obtain satisfying quality of results usually careful adjustments of the setup has to be performed. The work presented in this paper aims at improving the quality of such measurements at the GomSpace Sweden company. LÄS MER

  5. 4. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor

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

    Författare :Kasim Ali Haji; [2021]
    Nyckelord :RBR Simulation; CFD models of an RBR; Energy-efficient Industrial processes; Power number; Power consumption; RBR; rotating bed reactor; Experimental and simulation of an RBR; Empirical models of an RBR; Thrust force; Torque requirement; k-epsilon model of an RBR; SST k-omega model of an RBR.;

    Sammanfattning : Rotating bed reactors are used throughout the process industry. They are usedboth in the chemical industry and other industrial sectors, such as pharmaceuticals and the textile industry in decolorization due to by-products or contaminants.SpinChem AB manufactures rotary bed reactors (RBRs) to perform chemical reactions between liquids and solids.

  7. 5. Dimensioning of a cutter wheel bearings

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Kebin Xie; [2020]
    Nyckelord :cutter wheel; bearing; wear; scuffing; Archard equation; lubrication number; Reynold equation; Hertzian contact theory; impact load factor; FE model; Ansys; contact pressure on bearing;

    Sammanfattning : Mobile Miner 40V is a machine used for rock excavation and developed by Epiroc. This machine is equipped with a large cutter wheel to perform the excavation. After a test run, some surfaces associated with bearings within the cutter wheel were found to be damaged due to scuffing - severe sliding wear. LÄS MER
