    Sammanfattning : Below in the report, the various methods available to calculate the interaction formulas for bending moment and normal force in steel columns are examined. The standards compared are SS-EN 1993-1-1:2005 Annex A, SS-EN 1993-1-1:2005 Annex B, SS-EN 1993-1-1:2022, CEN/TS 1993-1- 101:2022 and Fpr EN 1993-1-3:2023. LÄS MER

  3. 2. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Trulsa Eriksson; [2023]
    Nyckelord :System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Sammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

  4. 3. Agile robotic arm for vertical applications - Evaluation, design and development

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Rasmus Gren; [2023]
    Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

    Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

  5. 4. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Hasan Al-Zubaidi; [2022]
    Nyckelord :Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Sammanfattning : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). LÄS MER

  7. 5. Weight prediction of flight control subsystem

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Joel Lundahl; [2022]
    Nyckelord :Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

    Sammanfattning : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. LÄS MER
