6. Electrification Of A Tiltrotator : Electrifying The Hydraulic Tilt Function
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. LÄS MER
7. Water emissions from fuel cell-powered construction equipment : Quantifying liquid water and water vapor emissions for sustainable construction equipment
Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : The construction sector is responsible for 20% of Greenhouse Gas (GHG) emissions, of whichdiesel-powered construction equipment are large contributors. Currently there are many ongoing Fuel Cell (FC) powered construction equipment projects as it is seen as an attractiveoption to power the futures zero-emission heavy-duty machines. LÄS MER
8. NVH analysis and optimization of electric powertrain
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. LÄS MER
9. Logistik inom anläggningsarbeten : En fallstudie av kostnader för arbetsplatstillskottstid
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : Logistik inom byggbranschen genomgår ständigt utveckling. Nya teorier testas och logistiken utvecklas i takt med att byggnadsmaterial och produktionsmetoder förändras. Tidigare studier visar att 30-35 % av ett projekts produktionskostnad består av slöseri som är direkt kopplat till bristfällig logistik. LÄS MER
10. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. LÄS MER
