  1. 1. Slurry Transportation of Ores and Industrial Minerals in a Vertical Pipe by Centrifugal Pumps - A Pilot-plan Investigation of Hydraulic Hosting

    Författare :Anders Sellgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : .... LÄS MER

  3. 2. Secondary currents in groundwater

    Författare :Maria Engström; Bo Nordell; Anders Sellgren; Clifford Voss; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The thesis concerns the small vertical water movements created by thermal convection and the Coriolis force acting on groundwater flows. These small flows are of importance to vertical transports of temperature, nutrients and contaminants that would not be spread in the way they are. LÄS MER

  4. 3. 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

  5. 4. 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

  7. 5. On integrated modularization in heavy-duty truck architecting

    Författare :David Williamsson; Ulf Sellgren; Anders Söderberg; Johan Malmqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modularization; Module; Product Architecture; Cyber-Physical System; Machine Design; Maskinkonstruktion;

    Sammanfattning : Road transports face increasing challenges with respect to safety, legislations on lower emissions and traffic congestion, as well as numerous business challenges related to paradigm shifts in technology, tightened delivery times and cost constraints. Combination of truck electrification and automation may be utilized to address some of these issues. LÄS MER
