  1. 1. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

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

    Författare :Clara Nermark; [2023]
    Nyckelord :Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

    Sammanfattning : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. LÄS MER

  3. 2. Modelling and Simulation of Complete Wheel Loader in Modelica : Evaluation using Modelon Impact software

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

    Författare :Paolo Teta; [2022]
    Nyckelord :Modelica; Wheel Loader; Mechanics; Object-orientation; Modelling; Simulation; Differential Algebraic Equations; Ordinary Differential Equations; Modelica; Hjullastare; Mekanik; Objektorientering; Modellering; Simulering; Differentialekvationer;

    Sammanfattning : Modelling and simulation of complex and multi-domain mechanical systems has become of major importance in the last few years to address energy and fuel consumption performance evaluation. The goal is to unify the available modelling languages aiming to improve scalability and easiness of handling complex multi-domain models. LÄS MER

  4. 3. Estimation of blocked forces from a rear drive unit (RDU) in a test rig fixture

    Master-uppsats, KTH/Teknisk akustik

    Författare :Sanjay Jayachandran; [2022]
    Nyckelord :Acoustics; Vibration; Sound; Mechanics; Blocked Forces; Transfer Path Analysis; Component-based TPA; Vibro-acoustics;

    Sammanfattning : In the modern world, vehicle manufacturers are not the sole producer of every component in a vehicle but instead assign different subsystems to various OEMs (Original Equipment Manufacturer). Subsystems such as Rear Drive Units (RDU), Power Transfer Units (PTU), E-drives etc. are developed separately and then integrated into the main vehicle. LÄS MER

  5. 4. Utveckling av mekanism för detektering och avlivning av råttor i avloppsmiljö

    M1-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Nils Hallhagen; Felix Bentzer; [2021]
    Nyckelord :RatTrap; avlivning; råtta; råttfälla; Nomor AB; avloppsmiljö; koldioxid; CO2; CO2-patron; attrahent; membranventil; trapetsskruv;

    Sammanfattning : Detta examensarbete är en fortsättning på ett tidigare utfört arbete där koncept på en avloppsmonterad råttfälla togs fram. Allteftersom människor i större utsträckning flyttar till städer blir råttor ett större problem. Råttor kan bära med sig sjukdomar och de kan orsaka omfattande skador. LÄS MER

  7. 5. Internal combustion engine durability monitor : Identifying and analysing engine parameters affecting knock and lambda

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Pontus Jääskö; Petter Morén; [2021]
    Nyckelord :Internal combustion engine; durability testing; data analysis; Otto engine; ignition; ignition timing; fuel injection; Air fuel ratio; partial least squares regression PLSR ; lambda; engine knock;

    Sammanfattning : This study has been performed at Powertrain Engineering Sweden AB (PES), a fully owned subsidiary of Volvo Cars Group, which is constantly working to develop and improve internal combustion engines. As part of this work, durability tests are performed to analyse the impact of wear on the engines. LÄS MER
