    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; active suspension; ride comfort; sky-hook; Hinf; multi-body simulations; on-track tests; Vehicle engineering; Farkostteknik;

    Abstract : Active secondary suspension in trains has been studied for a number of years, showing promising improvements in ride comfort. However, due to relatively high implementation and maintenance costs, active technology is not being used in service operation to a large extent. READ MORE

  4. 2. On Active Secondary Suspension in Rail Vehicles to Improve Ride Comfort

    Author : Anneli Orvnäs; Sebastian Stichel; Rickard Persson; Roger Goodall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail vehicle; active secondary suspension; ride comfort; sky-hook damping; H∞ control; multi-body simulations; on-track tests; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Abstract : One way to make rail vehicles a competitive means of transportation is to increase running speed. However, higher speeds usually generate increased forces and accelerations on the vehicle, which have a negative effect on ride comfort. With conventional passive suspension, it may be difficult to maintain acceptable passenger comfort. READ MORE
