6. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation
Sammanfattning : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. LÄS MER
7. Hydraulic Power Steering System Design in Road Vehicles : Analysis, Testing and Enhanced Functionality
Sammanfattning : Demands for including more functions such as haptic guiding in power steering systems in road vehicles have increased with requirements on new active safety and comfort systems. Active safety systems, which have been proven to have a positive effect on overall vehicle safety, refer to systems that give the driver assistance in more and less critical situations to avoid accidents.

8. Conceptual Design of Complex Hydromechanical Transmissions
Sammanfattning : This thesis explores the conceptual design process of complex hydromechanical transmissions for mobile working machines. Efficient methods for design optimisation and controller development are presented to support the final concept selection. LÄS MER
9. Fluid Power Applications Using Self-Organising Maps in Condition Monitoring
Sammanfattning : Condition monitoring of systems and detection of changes in the systems are of significant importance for an automated system, whether it is for production, transport, amusement, or any other application. Although condition monitoring is already widely used in machinery, the need for it is growing, especially as systems become increasingly autonomous and self-contained. LÄS MER
