  1. 1. 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.

  3. 2. An Investigation of the Iron-Ore Wheel Damages using Vehicle Dynamics Simulation

    Författare :Saeed Hossein Nia; Sebastian Stichel; Matti Rantatalo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-piece bogie; wear; RCF; prediction; traction; braking; heavy haul; simulation; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Maintenance cost is one of the important issues in railway heavy haul operations. For the iron-ore company LKAB, these costs are mainly associated with the reprofiling and changing of the wheels of the locomotives and wagons. The main reason for the wheel damages is usually surface initiated rolling contact fatigue (RCF) on the wheels. LÄS MER

  4. 3. On Heavy-Haul Wheel Damages using Vehicle Dynamics Simulation

    Författare :Saeed Hossein Nia; Sebastian Stichel; Carlos Casanueva; Per-Anders Jönsson; Ernesto Garcia Vadillo; KTH; []
    Nyckelord :wear; RCF; rolling contact; traction; braking; heavy-haul; FASTSIM; FaStrip; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Maintenance cost is one of the important issues in railway heavy-haul operations. In most of the cases, these costs are majorly referring to reprofiling and changing the wheels of the locomotives and the wagons. The main reason of the wheel damages is usually severe wear and/or surface initiated rolling contact fatigue (RCF). LÄS MER

  5. 4. Dynamic Vehicle-Track Interaction of European Standard Freight Wagons with Link Suspension

    Författare :Per-Anders Jönsson; Sebastian Stichel; Evert Andersson; Jerzy Piotrowski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; stiffness; dry friction; hysteresis; simulation; vehicle-track interaction; multibody; simulation; MBS; Vehicle engineering; Farkostteknik;

    Sammanfattning : The link suspension is the most prevailing suspension system for freight wagons in Central and Western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. LÄS MER

  7. 5. Evaluation and Modelling of Short Haul Intermodal Transport Systems

    Författare :Behzad Kordnejad; Sebastian Stichel; Bo-Lennart Nelldal; Sebastiaan Meijer; Johan Woxenius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road.
