  1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  3. 2. Patienters upplevelser av hur stomi påverkar deras sexuella hälsa : en litteraturöversikt

    Kandidat-uppsats, Sophiahemmet Högskola

    Författare :Ronja Jerkesten; Tove Björk; [2022]
    Nyckelord :Body image; Experiences; Person-centred care; Sexuality; Stoma; Kroppsuppfattning; Personcentrerad vård; Sexualitet; Stomi; Upplevelser;

    Sammanfattning : Bakgrund   Sexuell hälsa är en viktig del av människans liv och byggs upp av flera delkomponenter. För att inneha en god hälsa och välbefinnande krävs det att även den sexuella aspekten av hälsa är tillgodosedd. Diverse faktorer kan påverka den sexuella hälsan, däribland kirurgi. LÄS MER

  4. 3. Rheology of dense particle suspensions in linear over-damped flow

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Salar Zamani Salimi; [2021]
    Nyckelord :;

    Sammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

  5. 4. Grey Box Model of Leakage In Radial Piston Hydraulic Motors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Niklas Ydebäck; [2021]
    Nyckelord :Grey box; modeling; Radial piston; Bosch Rexroth; parameter estimation;

    Sammanfattning : This report covers the work and results of the thesis project in Mechanical Engineering from Luleå university of technology performed by Niklas Ydebäck. The objective of the thesis project is to research if it is possible, with general principles of fluid flow between components and the corresponding geometric constraints between them and just a few channels of data, to model the leakage of a radial piston hydraulic motor.

  7. 5. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Paul-Henrik Bull; [2021]
    Nyckelord :ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Sammanfattning : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. LÄS MER
