  1. 16. Traffic Induced Vibrations at Road-Bridge - Experimental and Numerical Analysis

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Byggnadsmekanik

    Author : Oskar Baggens; [2012]
    Keywords : Technology and Engineering;

    Abstract : In the north-east part of Lund, Sweden, the MAX IV facility is (in the event of writing this thesis) under construction. MAX IV is a synchrotron radiation facility which has a high requirement regarding low vibrations. Within this thesis a nearby road-bridge for the highway E22 was studied using experimental and numerical methods. READ MORE

  3. 17. Equivalent Dynamics Model of Ballasted Track Bed

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Said Daoud; Xie Guowei; Liu Xiaoming; [2012]
    Keywords : ABAQUS; Ballast; modeling; simulation; train-track; fracture mechanics;

    Abstract : Increase of track maintenance costs and change of track geometry are due to the vibration of ballasted railway. The aim of this thesis work is to model train-track system as a multiply degree of freedom systems by Lump Parameter Method. READ MORE

  4. 18. Parametric study of bridge response to high speed trains, ballasted track on concrete bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Shahbaz Rashid; [2011]
    Keywords : Ballast stiffness; transition zones; Railway bridges; the Swedish X2000 train; vertical deck acceleration; MATLAB-ABAQUS model; Finite element analysis.;

    Abstract : When a train enters a bridge, passenger sitting inside will feel a sudden bump in the track, which not only affect the riding comfort of the passengers but also put a dynamic impact on the bridge structure. Due to this impact force, we have very serious maintenance problems in the track close to the bridge structure. READ MORE

  5. 19. Vibration Analyses of a Wooden Floor-Wall Structure- Experimental and Finite Element Studies

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Joel Ejenstam; Ola Flodén; [2011]
    Keywords : Technology and Engineering;

    Abstract : Changes in the Swedish construction code introduced in 1994 enabled the construction of wooden multistorey buildings. This resulted in an increased need for knowledge about wooden structures in the building industry. The main issue in wooden framed buildings is disturbing vibrations and noise which propagate throughout the construction. READ MORE

  6. 20. Optimal Design of Bridges for High-Speed Trains : Single and double-span bridges

    University essay from KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVG

    Author : Carine Mellier; [2010]
    Keywords : Optimization; Vertical deck acceleration; Railway bridges; High-speed trains; Train Signature; Finite element analysis;

    Abstract : To deal with an increasing demand in transportation, trains are made longer and faster. Higher speeds imply higher impacts on bridges. Therefore, structures have to be designed to resist these new constraints. The Eurocode (2002) introduced additional checks for the design of high-speed railway bridges. READ MORE
