21. Fluid Power Pumps and the Electrification : With a Focus on Discrete Displacement Control in Load Handling Applications
Sammanfattning : More and more vehicles are being electrified. Mobile working machines and heavy trucks are not excluded, and these machines are often hydraulically intense. Electrification entails new requirements for the hydraulic system and its components, and these requirements must be taken into consideration. LÄS MER
22. On Electrified Fluid Power Systems in Mobile Machinery
Sammanfattning : High power density in combination with flexible power distribution possibilities and extreme robustness are reasons why fluid power has been the preferred technology in mobile machinery, such as excavators and cranes, since the mid-20th century. In principle, the machines have been powered by a combustion engine which powers a pump, with the output from the pump being distributed to different functions via valves. LÄS MER
23. Evaluation of Aircraft Actuator Technologies
Sammanfattning : The flight control actuation system is one of the most critical systems in an aircraft. A failure of this system cannot occur, since it would have catastrophic consequences. LÄS MER
24. Control Aspects of Complex Hydromechanical Transmissions : with a Focus on Displacement Control
Sammanfattning : This thesis deals with control aspects of complex hydromechanical transmissions. The overall purpose is to increase the knowledge of important aspects to consider during the development of hydromechanical transmissions to ensure transmission functionality. LÄS MER
25. Control of Hybrid Hydromechanical Transmissions
Sammanfattning : This thesis deals with control aspects of complex hybrid hydromechanical transmissions for heavy mobile working machines. Control problems are identified and solved to facilitate the implementation and use of these systems. LÄS MER
