1. 1. 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

3. 2. 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

4. 3. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

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

   Författare :Malin Strandberg; [2021]
   Nyckelord :Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

   Sammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

5. 4. Design of Eccentric Double Amplitude Vibration Drum Roller Shaft with Improved Mass Moment of Inertia : Product Development of Compaction Equipment

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

   Författare :Marika Blad; Alexander Tynnerstål Balog; [2020]
   Nyckelord :Eccentricity; mass moment of inertia; double amplitude feature; vibration; Excentricitet; masströghetsmoment; dubbelamplitud; vibration;

   Sammanfattning : Road construction is important to make transports safe and sustainable. To compact asphalt an amount of energy needs to be conducted into the material either by static pressure or dynamic vibrations. An asphalt-roller compact the material and increases its load-bearing capacity. LÄS MER

7. 5. Elbow Design, Servo Motor Selection and Control Implementation of the Agile Parallel Kinematic Manipulator

   Master-uppsats, Lunds universitet/Industriell Produktion

   Författare :Hampus Farmängen; Felix Lundblad; [2019]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame.
