  1. 16. Systems Engineering for Computing Systems at Accelerator based Research Facilities

    Författare :Thilo Friedrich; Martin Törngren; Gerrit Muller; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Engineering; control system; computing system; particle accelerator; research facility; Machine Design; Maskinkonstruktion;

    Sammanfattning : Large research facilities are major research enablers for expanding fields in various natural sciences. Traditionally built for physics and astronomy, nowadays fields like life sciences, medicine, molecular sciences and material sciences have become the driving forces, especially for particle accelerator based research facilities.

  3. 17. On synchronization of heavy truck transmissions

    Författare :Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER

  4. 18. Suspended forestry machines for sustainable forestry

    Författare :Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. LÄS MER

  5. 19. On Stability and Surge in Turbocharger Compressors

    Författare :Bertrand Kerres; Andreas Cronhjort; Mihai Mihaescu; Jörg Seume; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Radial Compressor; Stability; Surge; Hurst exponent; Fractals; Machine Design; Maskinkonstruktion;

    Sammanfattning : Turbochargers are used on many automotive internal combustion engines to increase power density. The broad operating range of the engine also requires a wide range of the turbocharger compressor. At low mass flows, however, turbo compressor operation becomes unstable and eventually enters surge.

  7. 20. Supporting complete vehicle reliability forecasts

    Författare :Julia Lindén; Ulf Sellgren; Anders Söderberg; Fredrik Elgh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability forecast; interactive function; operating conditions; Machine Design; Maskinkonstruktion;

    Sammanfattning : Reliability is one of the properties that customers of heavy trucks value highest.Dependent on all parts and functions of the vehicle, reliability is a complexproperty, which can normally be measured only towards the end of a developmentproject. At earlier development stages, forecasts can give valuable decision supportfor project planning. LÄS MER
