  1. 1. Conceptual design of hydraulic systems for automotive engine applications : simulation, optimisation and testing

    Författare :Jochen Pohl; Nicola Nervegna; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The main contribution of this thesis lies in the area of systems design, and especially of such systems that involve several engineering domains, so-called multidomain or heterogeneous systems. The design of these systems is concerned with a need for efficient tools, especially in the early conceptual phase of the development process. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Exploring technologies for service provision in automotive winter testing

    Författare :Mikael Nybacka; Jochen Pohl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development;

    Sammanfattning : Vehicles are becoming increasingly more complex in terms of, for example. Electronic Stability Program (ESP), Antilock Braking System (ABS), Traction Control System (TCS), and Active Rollover Protection (ARP), i.e. several different control systems that have to interact to perform well when driving.
