3. 2. Refined model for calculating the dynamic amplification factor for road bridges

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Jens Bergenudd; [2020]
   Keywords : Dynamics; Dynamic amplification factor; Dynamic impact factor; Platooning; Soil-structure interaction; Vehicle-bridge interaction; Technology and Engineering;

   Abstract : The objective of the thesis is to simulate and evaluate vehicle-bridge interaction (VBI) due to road surface irregularities and soil-structure interaction (SSI) with different vehicle models and suspension properties. Parameter studies will be carried out for integral and slab bridges. READ MORE

4. 3. Modelling and Simulation of a bridge interacting with a moving vehicle system

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Rui Duan; Jingrui Yang; [2013]
   Keywords : Vehicles-bridge coupling vibration; Dynamic system; D’Alambert principle; Euler–Bernoulli beam theory; Mode superposition method; Newmark-beta method;

   Abstract : The problem about the vibration of vehicles and bridge is mainly the problem of coupling vibration between the vehicles dynamic system and bridge dynamic system. The vehicles running on the bridge at some speed can make the bridge vibrate, at the same time the vibration of the bridge will also affect the vibration of the vehicles. READ MORE

5. 4. 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
