  1. 1. Hydraulic Power Steering System Design in Road Vehicles Analysis, Testing and Enhanced Functionality

    University dissertation from Institutionen för ekonomisk och industriell utveckling

    Author : Marcus Rösth; Jan-Ove Palmberg; Nick Vaughan; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Power Steering; Active Safety; Comfort function; Shuttering; Linear modelling; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Abstract : 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.

  2. 2. On Energy Efficient Mobile Hydraulic Systems with Focus on Linear Actuation

    University dissertation from Institutionen för ekonomisk och industriell utveckling

    Author : Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. READ MORE

  3. 3. Pressure Control in Hydraulic Power Steering Systems

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Alessandro Dell’Amico; Petter Krus; Victor Juliano De Negri; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : There is a clear trend in the vehicle industry to implement more safetyrelated functions, where the focus is on active safety systems and today the steering system is also involved. Steering-related active safety functions can only be realised with a steering system that allows electroniccontrol of either the road wheel angle or the torque required to steer the vehicle, called active steering.

  4. 4. Saving Energy in Construction Machinery using Displacement Control Hydraulics Concept Realization and Validation

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Abstract : 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. READ MORE

  5. 5. Fluid Power Systems for Mobile Applications with a Focus on Energy Efficiency and Dynamic Characteristics

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mikael Axin; Petter Krus; Birgitta Lantto; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis studies an innovative working hydraulic system design for mobile applications. The purpose is to improve the energy efficiency and the dynamic characteristics compared to load sensing systems without increasing the complexity or adding additional components.The system analysed in this thesis is referred to as flow control.
