  1. 26. Dynamic Train-Track Interaction: Linear and Non-Linear Track Models with Property Scatter

    Författare :Johan Oscarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic track properties; non-linear track properties; dynamic train-track interaction; Latin Hypercube; perturbation technique; full-scale and laboratory measurements;

    Sammanfattning : A numerical method was developed to investigate the vertical dynamic behaviour of a railway track subjected to the loading of a moving train. The numerical simulations are carried out in the time-domain with what is known as a moving mass model. LÄS MER

  3. 27. Simulation of Dynamic Interaction between Train and Turnout

    Författare :Elias Kassa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic train–turnout interaction; wheel–rail contact geometry; switches and crossings; multibody dynamics; contact forces;

    Sammanfattning : Dynamic train–track interaction is more complex in railway turnouts (switches & crossings) than on ordinary tangent or curved tracks. Multiple contacts between wheel and rail are common, and severe impact loads with broad frequency contents are induced when the nominal wheel–rail contact conditions are disturbed due to the continuous variation in rail profiles and the discontinuities in the crossing panel.

  4. 28. Train Based Automated Inspection for Railway Fastening System

    Författare :Praneeth Chandran; Matti Rantatalo; Rolf Dollevoet; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rail fastening system; clamps; visual inspection; differential eddy current sensor; machine learning; anomaly detection; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Rail transportation is a sustainable mode of transportation and is a key enabler of the socio-economic development of modern society through passenger and freight services. Growth in overall transport demand has led to railways experiencing higher demand on operational capacity, service quality, and safety. LÄS MER
