  2. 1. Tilting trains : Technology, benefits and motion sickness

    Author : Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

    Abstract : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. READ MORE

  4. 2. Tilting trains : Enhanced benefits and strategies for less motion sickness

    Author : Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; Vehicle engineering; Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

    Abstract : Carbody tilting is today a mature and inexpensive technology that allows higher train speeds in horizontal curves, thus shortening travel time. This doctoral thesis considers several subjects important for improving the competitiveness of tilting trains compared to non-tilting ones. READ MORE

  5. 3. Ride comfort and motion sickness in tilting trains

    Author : Johan Förstberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tilting train; Ride comfort; Motion sickness; Simulator; Experiments;

    Abstract : This thesis presents a systematic study of human responses to different motions and strategies of car body tilt control regarding ride comfort, working/reading ability and motion sickness on high-speed tilting trains. Experiments with test subjects were performed in a tilting train on curved track as well as in a moving vehicle simulator. READ MORE

  6. 4. Studying Buoy Motion for Wave Power : Experiments at the Lysekil Research Site

    Author : Simon Tyrberg; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Since 2002, the Division for Electricity at Uppsala University has been running the Lysekil project. The project is an attempt to construct and evaluate a technology for extracting electrical energy from the motion of ocean waves. The idea is to let this up-and-down motion drive a linear generator.

  7. 5. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

    Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
