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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Small-amplitude steady water waves with vorticity

    Författare :Evgeniy Lokharu; Vladimir Kozlov; Johan Thim; Tomas Sjödin; Mark Groves; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The problem of describing two-dimensional traveling water waves is considered. The water region is of finite depth and the interface between the region and the air is given by the graph of a function. We assume the flow to be incompressible and neglect the effects of surface tension. LÄS MER

  4. 3. Towards Subject Specific Aortic Wall Shear Stress : a combined CFD and MRI approach

    Författare :Johan Renner; Matts Karlsson; Toste Länne; Patrick Segers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The cardiovascular system is an important part of the human body since it transports both energy and oxygen to all cells throughout the body. Diseases in this system are often dangerous and cardiovascular diseases are the number one killer in the western world. LÄS MER

  5. 4. Extending MRI to the Quantification of Turbulence Intensity

    Författare :Petter Dyverfeldt; Tino Ebbers; Krishna Nayak; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence intensity; cardiovascular disease; blood flow; hemodynamics; magnetic resonance imaging; generalized phase-contrast MRI; turbulent flow; Medical technology; Medicinsk teknik; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.

  7. 5. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

    Författare :Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    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
