  1. 11. Efficient FE Modeling of Large Casted Parts

    University essay from KTH/Maskinkonstruktion

    Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

  3. 12. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  4. 13. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    University essay from KTH/Materialvetenskap

    Author : Caterina Radogna; [2023]
    Keywords : Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Abstract : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. READ MORE

  5. 14. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    University essay from Lunds universitet/Industriell Produktion

    Author : Christian Jaunviksna; [2023]
    Keywords : Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Abstract : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. READ MORE

  6. 15. Redesign of Adapted Crossmember

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gustaf Rudbeck; Philip Linder-Aronson; [2023]
    Keywords : Truck Crossmember; Power take off system; Frame; Lastbil; Tvärbalk; PTO; Ram;

    Abstract : This thesis aims to address the incompatibility issues between Scania's 600 mm silencers and the second position 2 o'clock PTO adapted crossmember, by exploring redesign possibilities. The goal is to enable the co-mounting of these components, expanding customization options and enhancing Scania's modularization capabilities. READ MORE
