  1. 1. Evaluation of MPC and PI control on a Tribometer : Design and comparison of control methods for a Pin-on-Disc Tribometer

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

    Författare :Ehab Ziad Raheem; Tore Malmström; [2023]
    Nyckelord :Control Theory; MPC; PI; PI-Cascade; Tribometer; Pin-on-Disc; Reglersystem; MPC; PI; PI-Kaskadreglering; Tribometer; Stift-På-Skiva;

    Sammanfattning : This thesis compares Model Predictive Control (MPC) and Proportional-Integral (PI) control in a pin-on-disc tribometer. The tribometer consists of a geared Direct Current (DC) motor driving a flywheel and a voice coil actuating a pin onto the surface of the flywheel. LÄS MER

  3. 2. 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

  4. 3. Improvement and verification of a pin-on-disc tribometer with variable speed and load

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Valentine Lin; [2023]
    Nyckelord :tribometer; friction; tribometer; friktion;

    Sammanfattning : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. 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. Redesign of a tribological pin-on-disc machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Michal Szumin; [2022]
    Nyckelord :tribometer; particulate matter; studded tyres; tyre-road contact; tribometer; partiklar; dubbdäck; kontakt mellan däck och väg;

    Sammanfattning : In contradistinction with road transport exhaust particulate matter (PM) emission, non-exhaust PM emission has not decreased substantially in recent years. One source of non-exhaust PM emission is studded tyre-pavement contact. LÄS MER
