  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  3. 2. Koppling för kraftuttag : En stelkroppsdynamisk simulering av ett kopplingsförlopp.

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Cristian Croitoru; Mikael Rydersten; [2023]
    Nyckelord :Kraftuttag; MSC Adams; Klokoppling; Simulering; Stelkroppsdynamik;

    Sammanfattning : Studien handlar om utveckling av ett flexibelt klokopplingssystem tillsammans med SwePart Transmissioner AB. Principen bygger på att en hylsa med utvändiga splines belastas i inkopplingsförloppet. Hylsan skapar en axiell rörelse som sedan absorberas av fjädrar vilket utgör flexibiliteten i klokopplingen.

  4. 3. Polarizability and Orientation Dynamics of Small Proteins

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Ebba Koerfer; [2022]
    Nyckelord :Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Sammanfattning : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. LÄS MER

  5. 4. Assessment of optimal suspension systems with regards to ride under different road profiles

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Adithya Murali; Pratik Hindraj Vaje; [2021]
    Nyckelord :Ride comfort; Handling; Road profiles; ADAMS; Shaping filter method; Sinusoidal approximation method; Coherence; ISO 8608; Acceleration PSD s; Genetic Algorithm optimisation; ISO 2631.; åkkomfort; Kurvkörningsegenskaper; Vägprofiler; ADAMS; Formningsfiltermetod; Sinusformad approximationsmetod; Koherens; ISO 8608; Acceleration PSDs; Genetisk algoritmoptimering.;

    Sammanfattning : Passenger ride vibration comfort is a critical aspect to consider while developing any vehicle and there is a need to understand how the occupants would be affected when driving on different road profile roughness. Hence, road profile generation is critical as road profiles are used as inputs to simulation tools to investigate vehicle dynamic behaviour in depth. LÄS MER

  7. 5. A bonded discrete element approach to simulate loading with hydraulic mining excavators

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

    Författare :Carl Andersson; [2021]
    Nyckelord :DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

    Sammanfattning : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. LÄS MER
