1. 1. Quantifying Middle Frequency Transient Currents in Power Consuming Devices

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Alex Lundvall; Vincent Sollie; [2021]
   Keywords : ;

   Abstract : 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. READ MORE

3. 2. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Jacob Wallersköld; Johan Appelros; [2021]
   Keywords : wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

   Abstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

4. 3. Energy efficient oil supply for clutch actuation in planetary transmissions

   University essay from Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska fakulteten

   Abstract : The improvement potential of the oil supply system used in Volvo CE's planetary transmission PT9 is studied in this thesis. The main focus was to improve the energy efficiency of the system while at the same time satisfying all of the system's functional demands. READ MORE

5. 4. Powertrain dynamic torque reduction using clutch slip control

   University essay from KTH/Fordonsdynamik; KTH/Farkost och flyg

   Author : Marcus Engman; Andreas Szilassy; [2014]
   Keywords : ;

   Abstract : The torque dynamic caused by the firing pulse from diesel engines set high robustness demands for gearboxes and final drives in today’s heavy duty trucks. If these dynamic loads could be eliminated or dampened, the driveline can be built lighter because of the lower demands which in turn would save fuel for the driver and material cost for the manufacturer.
