11. Efficiency verification of an electromechanical linear actuator
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Cascade Drives has developed an electromechanical linear actuator with a patented feature which allows for load sharing between multiple pinions interacting on the same rack. This arrangement has proven resilient for shock loads, and allows for compact gearbox designs with very high load rating. LÄS MER
12. The role of location of low inertia in power systems
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

13. Modelling of electromechanical motors for turret and barrel control in main battle tanks
Master-uppsats, KTH/FordonsdynamikSammanfattning : In this master thesis the dynamics of a modern main battle tank's turret traverse and gun elevation have been modelled. The models of dynamic motion have been coupled to two different types of electric motors, namely a direct-current motor and an induction motor. LÄS MER
14. Reliability Assessment of Electro-mechanical Linear Actuator
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Syftet med denna avhandling var att uppskatta livslängden och tillförlitligheten för det elektromekaniska linjära ställdonet genom att använda metoder för sannolikhet och statistik, med fokus på att fastställa svagare områden som kan förbättras för att inkludera dessa förbättringar i kommande generation. Bedömningen gjordes kvantitativt och kvalitativt. LÄS MER
15. Research and Testing of an Electromechanical solution for Vibration Assisted Drilling of Aerospace Materials
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/SolcellsteknikSammanfattning : This thesis considers vibration drilling in aerospace materials. The tolerances of the drilled holes in aerospace industry are very low since hole quality is an important factor. Conventional methods of drilling create long ribbon formed chips that increases the heat formation and decreases the hole quality. LÄS MER
