1. Evaluation of electric actuation for fighter aircraft
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. LÄS MER
2. Mot elektrifiering av bandförslutningsenhet SBH5
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Föreliggande projekt har genomförts mot Sund Birsta AB. Projektet innefattade förberedande arbeten för elektrifiering av Sund Birstas hydrauliska bandförslutare SBH5. LÄS MER
3. Omkonstruktion av bockverktyg : Från hydraulisk till elektrisk drivning
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : A hydraulic bending tool is used in the manufacturing of transformer windings at Hitachi ABB Power Grids. This tool is used to create a pitch between the turns in the winding, a process which demands very strict tolerances during bending. Hitachi/ABB believes that the current tool is quite inconvenient and, in some cases, dangerous to use. LÄS MER
4. Quantifying Middle Frequency Transient Currents in Power Consuming Devices
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. LÄS MER
5. Electrically powered manoeuvring of water jets
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.
