1. Investigation of performance and surge behavior of centrifugal compressors through CFD simulations
Master-uppsats, KTH/MekanikSammanfattning : The use of turbocharged Diesel engines is nowadays a widespread practice in the automotive sector: heavy-duty vehicles like trucks or buses, in particular, are often equipped with turbocharged engines. An accurate study of the flow field developing inside both the main components of a turbocharger, i.e. LÄS MER
2. Model Predictive Control Using Neural Networks : a Study on Platooning without Intervehicular Communications
Master-uppsats, Linköpings universitet/ReglerteknikSammanfattning : As the greenhouse effect is an imminent concern, motivation for the development of energy efficient systems has grown fast. Today heavy-duty vehicles (HDVs) account for a growing part of the emissions from the vehicular transport sector. LÄS MER
3. Improved Functionality for Driveability During Gear-Shift : A Predictive Model for Boost Pressure Drop
Magister-uppsats, Linköpings universitet/FordonssystemSammanfattning : Automated gear-shifts are critical procedures for the driveline as they are demanded to work as fast and accurate as possible. The torque control of a driveline is especially important for the driver’s feeling of driveability. LÄS MER
4. Computationally Efficient Model for On-Board Simulation of Heavy Duty Diesel Engines
Master-uppsats, Institutionen för systemteknik; Tekniska högskolanSammanfattning : Simulating the translatory motion of a vehicle during a gear shift gives a good basis to evaluate performance and comfort of a gear shift. This evaluation can be used for gear shifting strategy in an automatic transmission. LÄS MER
5. Modeling and Control of Opticruise - a Pneumatic Force Actuator
Uppsats för yrkesexamina på avancerad nivå, KTH/ReglerteknikSammanfattning : Opticruise is an automated transmission system for manual gear boxes. The length stroke is a part of the Opticruise system, in which the mechanical gear shifting process is performed by pneumatic actuators. To reduce piston velocity before the cylinder walls are reached, an oil damper is attached to the pneumatic actuator. LÄS MER
