  1. 1. Modelling and analysis of hydropower generator rotors

    Författare :Rolf Gustavsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : In almost all production of electricity the rotating machines serves as an important part of the energy transformation system. In hydropower units, a hydraulic turbine connected to a generator converts the potential energy stored in the water reservoir into electrical energy in the generator. LÄS MER

  4. 3. Om folkhögskolans dynamik : Möten mellan olika bildningsprojekt

    Författare :Rolf Berndtsson; Staffan Larsson; Bernt Gustavsson; Gunnar Sundgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Folk high school; The generally oriented course; Projects of Bildung; Selfeducation; Self-development; Self-rehabilitation; Qualification; Dynamic; Process; Power and Bildung;

    Sammanfattning : This study is describing the projects of Bildung which are possible to identify with the students and the teachers at two folk high schools and the meeting between those projects in the classrooms. Another purpose is to describe and analyze processes, which arise when teachers, students and folk high school as an institution come together. LÄS MER

  7. 5. Rotordynamic Modeling and Characterization of Support Elements in Vertical Machines

    Författare :Gudeta Benti; Jan-Olov Aidanpää; Rolf Gustavsson; Ilmar Santos; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rotordynamic; Support Element; Bearing; Squeeze Film Damper; Hydropower; Vertical Machine; Machine Design; Maskinkonstruktion;

    Sammanfattning : The dynamic properties of rotating machines are highly influenced by interconnecting devices, such as bearings, seals, or squeeze-film dampers. They play a significant role in regulating the characteristics of the interaction between the rotating and stationary parts of the machines. LÄS MER
