  1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Kaibin Wen; [2023]
    Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER

  3. 2. Challenges and Metallurgical Benefits of Implementing Metal Additive Manufacturing : A Case Study on Excavator Bucket Teeth Comparing Sand Casting with Additive Manufacturing

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sam Thai; Michael Thunberg; [2023]
    Nyckelord :Challenges; Electron Beam Melting; Metal Additive Manufacturing; Metallurgy; Microstructure; Porosity; Qualification; Sand Casting;

    Sammanfattning : Introduction: Production systems go through changes over time and there are different factors driving the change. Metal Additive manufacturing (AM) could be a factor with industries that already havetaken interest in the manufacturing technique. LÄS MER

  4. 3. Development of acomplex robot structure : Development and analysis of a cast triple traction system for the robotoperating at CERN facilities

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Gerard Aliana Cervera; [2023]
    Nyckelord :CERNBot; Traction; Topology optimization; Sand casting;

    Sammanfattning : All devices working in hazardous environments have specific requirements to reduce the intervention of human power as much as possible. The robot that this thesis is focused on is no exception to this rule. LÄS MER

  5. 4. Torkning av gjutsand i en fluidiseradbädd. : Energioptimering, flödeshastighet, gastemperatur och klimateffekter.

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Linnéa Bogren; [2022]
    Nyckelord :energioptimering; flödeshastighet; gastemperatur; klimateffekter; fluidiserad bädd; gjutsand;

    Sammanfattning : En studie har genomförts för att undersöka möjligheterna att torka gjutsand i en fluidiserad bädd. Sand är ett ändligt material och i gjutprocessen används tonvis gjutsand årligen. Volvo Powertrain Production har ett gjuteri i Skövde där de undersöker om de kan återanvända sin gjutsand. LÄS MER

  7. 5. Automatic Crack Detection in Sand Molds Using Image Processing and Convolutional Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Tim Andersson; [2022]
    Nyckelord :automatic crack detection; convolutional neural network; image processing; sand casting;

    Sammanfattning : Sand casting is used to manufacture large metal workpieces. The processing is executed by pouring molten metal into a sand mold. During the process, the mold is subjected to mechanical and thermal stress. It is of economic interest to inspect the molds for defects that can affect casting results, in the worst case leading to discarded products. LÄS MER
