4. 3. 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
