1. 1. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :Henrik Malm; [2016]
   Nyckelord :SSI; Soil-structure interaction; Structural dynamics; High-speed railway bridges; Impedance; Receptance; Finite element method; Portal frame bridge; Technology and Engineering;

   Sammanfattning : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. LÄS MER

3. 2. Soil-structure interaction of end-frames for high-speed railway bridges

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Johan Östlund; [2016]
   Nyckelord :Dynamics; SSI; Soil-structure interaction; Soil-bridge interaction; HSR; High-speed railway; Impedance; Receptance; End-frame bridge; Dynamik; SSI; Jord-struktur interaktion; Jord-bro interaktion; HSR; Höghastighetsbana; Höghastighetståg; Impedans; Receptans; Ändskärmsbro;

   Sammanfattning : In this thesis, the influence of soil-structure interaction (SSI) of end-frame bridges for high-speed railways was studied. Impedance functions, representing the SSI, was calculated and analyzed. The impedance functions were applied to end-frame bridge models which were analyzed for use in HSR. LÄS MER

4. 3. 3D-models of railway track for dynamic analysis.

   Master-uppsats, KTH/Transportvetenskap

   Författare :Huan Feng; [2011]
   Nyckelord :track dynamics; railway track modelling; finite element analysis; receptance;

   Sammanfattning : In recent decades, railway transport infrastructures have been regaining their importance due to their efficiency and environmentally friendly technologies. This has led to increasing train speeds, higher axle loads and more frequent train usage. LÄS MER

5. 4. Fluid-Structure Interaction Analysis for Hydrodynamic Parameters in Semi-Submerged Axisymmetric Buoy

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Mohamed Salim Ramadan; Sorawan Saichua; [2010]
   Nyckelord :Added mass; Added damping; ALE; COMSOL Multiphysics; Fluid-structure interaction FSI ; Two-phase flow;

   Sammanfattning : The dynamic heave responses of the semi-submerged axisymmetric buoy of two different geometries to the excitations equivalent to impulse excitation technique were represented by mechanical single-degree-of-freedom models. Founded on linear and 2-dimensional potential flow theory, the fluid-structure interactions were modeled and simulated with finite element approach. LÄS MER
