  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. Master Thesis - Towards a Virtual Climate Chamber : A numerical study using CFD software

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Yuvarajendra Anjaneya Reddy; [2020]
    Nyckelord :CFD; Ansys FLUENT; Power Spectral Density; Turbulence quanitification; Digital Twin;

    Sammanfattning : For each generation of electronic equipment there is a trend towards higher power den-sities. Increased heat generation is an undesired consequence that the thermal design unit in a company must handle. The goal of thermal design engineer/unit is to utilizethe same volume to more efficiently transfer more heat from the equipment. LÄS MER

  4. 3. Evaluation of a digitial displacement pump in a load haul dump application

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Jayasurya Madhusudanan; [2019]
    Nyckelord :Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

    Sammanfattning : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. LÄS MER

  5. 4. Dynamic Modeling and Simulation of Digital Displacement Machine

    Master-uppsats, Fluida och mekatroniska system; Tekniska högskolan

    Författare :Sanjib Chakraborty; [2012]
    Nyckelord :Digital Displacement machine; Digital Hydraulics; Hopsan; Digital fluid power; Generic model;

    Sammanfattning : Improved efficiency, better controllability and low noise are the most demanding features form a displacement machine now-a-days. Most of the conventional displacement machines are basically a reciprocating pumping element controlled by valve plates or with the help of check valve [1]. LÄS MER

  7. 5. Digital Implementation of a Laser Doppler Perfusion Monitor

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Ola Larsson; [2006]
    Nyckelord :Digital Laser Doppler DSP Perfusion FFT PSD Perimed;

    Sammanfattning : Under 20 års tid har Perimed AB utvecklat och tillverkat LDPM- och LDPI-instrument som är baserade på en analog filterkonstruktion. De analoga komponenterna i konstruktionen är komplexa och icke-linjära med hänsyn till frekvens och de driver även med temperaturen. LÄS MER
