  1. 1. Efficient FE Modeling of Large Casted Parts

    Master-uppsats, KTH/Maskinkonstruktion

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

    Sammanfattning : 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. LÄS MER

  3. 2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Jacobsson Trönndal; [2023]
    Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER

  4. 3. Variations in material properties of grey cast iron and its impact on tool wear

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Andreas Söderholm; [2021]
    Nyckelord :Grey cast iron; hard inclusions; tool wear; machinability; graphite structure.; Technology and Engineering;

    Sammanfattning : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. LÄS MER

  5. 4. Tyresö gymnasium, en restaurering.

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Ida Thunström; [2014]
    Nyckelord :Bostäder; Restaurering; Tyresö gymnasium; Renovering; Lägenhet; Kollektiv; Patina; Historia; Konservering;

    Sammanfattning : Restaurering handlar om att spara något av det existerande och använda sig av det, om det så är en struktur, ett minne, en detalj eller den inre luftmassan. Frågan är varför man i vissa fall sparar en träbit från 1700-talet som är sned och sliten, när man skulle kunna byta ut den till en rak istället, men måla den i samma kulör. LÄS MER

  7. 5. Design and development of a new invented doctor blade : Design och utveckling av nyuppfunnet kräppningsblad

    Magister-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Niklas Öhrn Sten; [2014]
    Nyckelord :Doctor blade; Design; Development; Kräppningsblad;

    Sammanfattning : This report contains the development and construction of a new patented doctor blade. A doctor blade is used when creping soft paper from a large rotating Yankee cylinder. At the current state the doctor blade are in use for four to six hours before it needs to be switch due to wearing, stopping the production of soft paper. LÄS MER
