  1. 6. On Ground and Structural Vibrations Related to Railway Traffic

    Författare :Johan O. Jonsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave propagation; wave field excitation; soil structure interaction; structural vibration; ground vibration; traffic vibration;

    Sammanfattning : The continuous development and integration of railway infrastructure, especially within urban areas, can cause ground and building vibrations to reach levels that bring discomfort to people. The growing risk of damage to buildings located in areas prone to ground vibration should not be underestimated. LÄS MER

  3. 7. Efficient Modelling Techniques for Vibration Analyses of Railway Bridges

    Författare :Christoffer Svedholm; Costin Pacoste; Pedro Museros; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway bridge; High-speed train; Closed-form solution; Non-proportional damping; Complex mode;

    Sammanfattning : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges, mainly because high-speed trains can cause resonance in the bridge superstructure. Dynamic simulations, often utilising time-consuming finite element analysis (FEA), have become essential for avoiding such problems. LÄS MER

  5. 9. Interpretation of Railway Track Alignment Measurements in a Geodynamic Perspective

    Författare :Jonas Majala; Jan Laue; Thorkild Maack Rasmussen; Kenneth Viking; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; Railway; Frequency; Track measurement; Geoteknik; Soil Mechanics;

    Sammanfattning : The development in society means that infrastructure like ballasted railway systems are facing challenges due to request for increased number of high-speed trains and heavier freight trains. This implies that ballasted railways get an increased impact from larger dynamic loads. LÄS MER

  7. 10. Train–Bridge Interaction : Literature Review and Parameter Screening

    Författare :Therese Arvidsson; Raid Karoumi; Costin Pacoste; Weiwei Guo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; vibration; railway bridge; bridge deck acceleration; moving load; train–bridge interaction; vehicle model; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : New railway lines are continuously being constructed and existing lines are upgraded. Hence, there is a need for research directed towards efficient design of the supporting structures. LÄS MER
