  1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

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

    Författare :Viktor Lange; [2023]
    Nyckelord :Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER

  3. 2. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Johan Samuelsson; [2022]
    Nyckelord :Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Sammanfattning : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. LÄS MER

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Johan Blomberg; Alfred Sörgårn; [2021]
    Nyckelord :flood; c3c; capacity; concrete; concrete blocks; exceptional loads; eurocode; floating debris; water load; overturning; sliding; friction; översvämning; c3c; kapacitet; betong; betongblock; exceptionella laster; eurokod; drivgods; vattenlast; stjälpning; glidning; friktion;

    Sammanfattning : Floods are the natural disaster that causes the most deaths and economic damage in the world. Sweden has been relatively spared from casualties in connection with floods, but the material damage is significant. In the future, larger and more frequent floods are expected. LÄS MER

  5. 4. Floor Guide for Sliding Doors

    Master-uppsats, Lunds universitet/Innovation

    Författare :Elin Friberg; Jennie Walfridson; [2020]
    Nyckelord :Product development; Assa Abloy; floor guide; friction; noise; Technology and Engineering;

    Sammanfattning : This Master Thesis, executed in collaboration with Assa Abloy Entrance Systems, addresses issues and desirable features with the currently used floor guide, and several final concepts, in terms of short-term and mid-term solutions, are presented after following the product development process. The floor guide's main purpose is to keep the door leaves of an automatic sliding door running smoothly on correct track without causing any noise. LÄS MER
