  2. 1. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering

    Author : Björn Eriksson; Jan-Olov Palmberg; Jonas Larsson; Jochen Pohl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; mode switch; energy efficient; independent metering; split spool; poppet; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. READ MORE

  4. 2. Mobile Fluid Power Systems Design : with a Focus on Energy Efficiency

    Author : Björn Eriksson; Jan- Ove Palmberg; Heikki Handroos; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This work deals with innovative energy efficient fluid power systems for mobile applications. The subjects taken up concern to what extent and how energy losses can be reduced in mobile working hydraulics systems. Various measures are available for increasing energy efficiency in these kinds of systems. READ MORE

  5. 3. On Fluid Power Piston Pumps : With Special Reference to Flow Ripple Reduction

    Author : Maria Pettersson; Linköpings universitet; []
    Keywords : ;

    Abstract : Among the major disadvantages of fluid power systems, leakage and an unpleasant sound level can be mentioned. Both drawbacks increase with increasing pressure ripple. Functional problems may be caused, even fatigue and breakdown. A main source of noise is hydrostatic pumps. READ MORE

  6. 4. Fluid Power Pumps and the Electrification : With a Focus on Discrete Displacement Control in Load Handling Applications

    Author : Samuel Kärnell; Liselott Ericson; Petter Krus; Maria Pettersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  7. 5. On valve controlled fluid power systems : flow amplifier and percussive rock drilling

    Author : Henrik Pettersson; Matti Vilenius; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis discusses how the design of hydraulic systems and components can be made to meet the demands of a future market in terms of efficiency, flexibility and cost. It also discusses how computer simulation can support the designer to get a higher knowledge of the system and to make the design phase more efficient. READ MORE
