  1. 6. Investigate the track gauge widening on the Iron-ore line and suggest maintenance limits

    University essay from KTH/Spårfordon

    Author : Jesper Flodin; [2020]
    Keywords : ;

    Abstract : Iron ore export remains a major player in the Swedish economy to date, with 90% of all iron ore produced in Europe stemming from the relatively small northern country. A large amount of this ore is transported from the mines to harbours for world-wide freight on railways. READ MORE

  3. 7. Estimation of wheel-rail friction at vehicle certification measurements

    University essay from KTH/Spårfordon

    Author : Márton Pálinkó; [2016]
    Keywords : ;

    Abstract : In certification of new rail vehicles with respect to running characteristics, a wide variety of operating conditions needs to be considered. Behaviour on straight and curved tracks, including twisted tracks at various speeds, is of great importance. However, the wheel-rail friction should always be high corresponding to dry conditions.

  4. 8. The potential of Fluid Dynamic Absorbers for railway vehicle suspensions

    University essay from KTH/Spårfordon

    Author : Visakh V Krishna; [2016]
    Keywords : ;

    Abstract : The main running objectives concerning the vertical dynamics of passenger rail vehicles are ride comfort and safety. The goal of this thesis is to employ the use of a Fluid Dynamic Absorber to minimize the vertical acceleration of the car body while minimizing the dy-namic force fluctuations in the wheel rail contact.

  5. 9. Running Dynamics for a Maintenance Railway Vehicle

    University essay from KTH/Järnvägsteknik

    Author : Michael Gustafsson; [2014]
    Keywords : ;

    Abstract : BS Verkstäder has developed a new railway maintenance vehicle, MTR2000, which is in the process of authority approval. A part of the approval is the running dynamics of the vehicle which for maintenance vehicles following SS‐EN 14033‐1 can be evaluated using a simulation model of the vehicle, which is verified by comparing simulation results to measurements from a vehicle test.

  6. 10. SUSPLAB : A suspension component simulation tool for MATLAB

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Carl Fredrik Pellfolk; [2013]
    Keywords : ;

    Abstract : A GUI-assisted (Graphical User Interface) suspension component simulation tool has been developed in the computer package MATLAB. The purpose is to provide an example of a lightweight and expandable platform for educational use in the field of vehicle dynamics and suspension components. READ MORE
