  1. 16. An Optimization Framework for Elastomer Machine Tools

    Master-uppsats, Lunds universitet/Innovation

    Författare :Love Montan Larsson; [2022]
    Nyckelord :Polyurethane; Elastomer; packaging industry; Design of Experiments; Finite Element Analysis; Response Surface Methodology; multiple linear regression analysis; Additive Manufacturing.; Technology and Engineering;

    Sammanfattning : A framework for optimizing the design of elastomer packaging machine tools, so­ called plunge tools, has been developed and has reached a proof­of­concept state in this thesis. The framework indicates the capability of decreasing prototype expenses and total development time of new plunge tools by roughly three times compared to the existing iterative design methodology.

  3. 17. UV Curable Polymers for use in Additively Manufactured Energetic Materials

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Alexis Delorme; [2022]
    Nyckelord :Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

    Sammanfattning : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. LÄS MER

  4. 18. Totalkostnad för ägande av produktionsutrustning med fokus på hållbar utveckling

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Filip Lennartsson; Hampus Jonasson; [2021]
    Nyckelord :Total cost of ownership; TCO; sustainable development; 2-component polyurethane lacquer; chemicals; carbon dioxide emissions.;

    Sammanfattning : Companies today strive to lower their climate footprint in their daily work. It is therefore important for them to consider sustainable development when investing in new production equipment. The purpose of the study is to create a greater understanding to which parameters should be involved in a TCO with focus on sustainable development. LÄS MER

  5. 19. Artificial Spider Web : Selection of Polymeric Materials for Special Effects Applications

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Hugo Huas; Titouan Jérome; [2021]
    Nyckelord :;

    Sammanfattning : Artificial  spider  webs  are  a  challenge  for  the  special  effects  companies.   The natural  spider webs  are  displaying  incredible  mechanical  properties  combined with  a  low  density  and  a  high stickiness making them hard to reproduce. LÄS MER

  7. 20. Neural Network-based Optimization of Solid- and Fluid Mechanical Simulations

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Pablo Jeken Rico; [2021]
    Nyckelord :PU Foaming Simulations; Computer Vision; Artificial Neural Networks; Polyuretanskumning Simuleringar; Computer Vision; Artificiella Neurala Nätverk;

    Sammanfattning : The following project deals with the optimization of simulation parameters such as the injection location and pitch angle of polyurethane foaming simulations using artificial neural networks. The model's target is to predict quality variables based on the process parameters and the geometry features. LÄS MER
