  1. 1. Impact of Frame Stiffness on Tribological Behaviour of Sliding Interfaces

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

    Författare :Nisha Singh; [2023]
    Nyckelord :coefficient of friction; friction-vibration interaction; stiffness; tribometer; vibrations; friktionskoefficient; friktion-vibrationsinteraktion; styvhet; tribometer; vibrationer;

    Sammanfattning : Friction and wear have been concerns to industrialists, scientists and environmentalist for several decades. Many robust models have been developed to address friction and wear and their dependency on various parameters. Numerous experiments have been conducted in the past to model friction and wear.

  3. 2. Evaluation of Numerically Developed Models of an ECB for Estimating the Braking Torque on the SkiCrosser

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

    Författare :Filip Andersson; William Marin; [2023]
    Nyckelord :;

    Sammanfattning : Cross-country skiing is a popular method of exercising that builds strength, stamina and engages the entire body. As cross-country skiing requires snow to be present, it is typically only performed during the winter, resulting in a rather limited way of exercising. LÄS MER

  4. 3. Koncept för att testa däckslitage

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

    Författare :Philip Missuna; [2023]
    Nyckelord :Microparticles; Tribometer; Tire; Camber; Däck; Mikropartiklar; Tribometer; Cambervinkel;

    Sammanfattning : Denna rapport omfattar utveckling av en rigg för att testa slitage av däck. Detta sker genom omkonstruktion av existerande pinne-på-skivatribometer rigg som man finner hos Kungliga Tekniska Högskolan. LÄS MER

  5. 4. Modeling of a ball contact with a coated plate

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

    Författare :Mohammadreza Saeedi; [2023]
    Nyckelord :Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Sammanfattning : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. LÄS MER

  7. 5. Brotthhållfastheten på monolitiska broar av flerskiktad zirkonia med olika konnektordimensioner och placering i en disk - En pilotstudie

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Iman Echreshavi; Linda Alsabti; [2022]
    Nyckelord :Connector dimension; Monolithic zirconia; Multi-layered zirconia; Yttria-stabilized zirconium dioxide; Y-TZP.;

    Sammanfattning : Purpose: The purpose of this study was to evaluate the fracture strength of monolithic FDPs of multi-layered zirconia (YML) with different connector dimensions and placement in the disc. Material and method: Forty 3-unit monolithic anterior FDPs were produced, 212223, and divided in four groups (n=10) based on the different connector dimensions and strategies for placement in KATANATM Zirconia Yttria Multi-Layered (YML)-disc.
