  1. 11. Carbody and Passengers in Rail Vehicle Dynamics

    Författare :Pelle Carlbom; KTH; []
    Nyckelord :Rail-Vehicle Dynamics; Human-Body Dynamics; Ride Comfort; Structural Dynamics;

    Sammanfattning : The carbody plays an important role in rail vehicle dynamics.This thesis aims atdeveloping validated modelling methods tostudy its dynamics, how it is excited on trackand how itinteracts with the passengers. The primary interest is ridecomfort,considering vibrations up to 20 Hz. LÄS MER

  3. 12. Tilting trains : Technology, benefits and motion sickness

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

    Sammanfattning : 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. LÄS MER

  5. 14. Tilting trains : Enhanced benefits and strategies for less motion sickness

    Författare :Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 15. Mechatronic aspects of an innovative two-axle railway vehicle

    Författare :Rocco Libero Giossi; Sebastian Stichel; Tian Xiang Mei; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Within the Shift2Rail research program the goals for a sustainable growth of the railway sector are set. Among these are substantial reduction of Life Cycle Costs, improved reliability and energy efficiency, the reductionof noise emissions, and the achievement of full interoperability of the rolling stock.
