  2. 1. On the Modelling of Train Induced Ground Vibrations with Analytical Methods

    Author : Anders Karlström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; train; wave propagation; dynamic flexibility; trench; railway track; vibration isolation; wave barrier; soil-structure interaction;

    Abstract : A novel analytical approach to model train induced ground vibrations is proposed. Integral transform solutions are combined with series solutions to obtain fast numericalalgorithms, where a particular designed boundary condition for finite regions is seen to enable the solution procedure.

  4. 2. On Ground and Structural Vibrations Related to Railway Traffic

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

    Abstract : 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. READ MORE

  5. 3. Train-Induced Ground Vibration and Its Prediction

    Author : Mehdi Bahrekazemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis based on a series of ground vibrationmeasurements at different sites presents two differentsemi-empirical models for prediction of ground-borne vibrationdue to train traffic. Ground-borne vibration due to train traffic may causeannoyance to people who live nearby the track or interfere withthe operation of sensitive equipment inside the buildings. READ MORE

  6. 4. Difficulties to Read and Write Under Lateral Vibration Exposure : Contextual Studies Of Train Passengers Ride Comfort

    Author : Jerker Sundström; Shafiquzzaman Khan; Neil J. Mansfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lateral vibrations; passenger activities; reading; writing; sitting posture; frequency weighting; rated difficulty; field study; laboratory study; transient vibrations; stationary vibrations.; Vehicle engineering; Farkostteknik;

    Abstract : Many people use the train both as a daily means of transport as well as a working place to carry out activities such as reading or writing. There are, however, several important factors in this environment that will hamper good performance of such activities. READ MORE

  7. 5. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice

    Author : Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration mitigation; high-speed railway bridges; damping devices; retrofit; numerical analysis; hybrid simulation; field experiment; vibrationsdämpning; järnvägsbroar för höghastighetståg; dämpare; eftermonteringsmetod; numerisk analys; hybridsimulering; fältförsök; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. READ MORE
