Dynamic Response Analysis of Geogrid Reinforced Embankment Supported by CFG Pile Structure During a High-Speed Train Operation

Dynamic Control of High-speed Train following Operation

Both safety and efficiency should be considered in highspeed train following control. The real-time calculation of dynamic safety following distance is used by the following train to understand the quality of its own following behaviour. A new velocity difference control law can help the following train to adjust its own behaviour from a safe and efficient steady-following state to another one ...

Three-Dimensional Dynamic Analyses of Track-Embankment-Ground System Subjected to High Speed Train Loads

A three-dimensional finite element model was developed to investigate dynamic response of track-embankment-ground system subjected to moving loads caused by high speed trains. The track-embankment-ground systems such as the sleepers, the ballast, the embankment, and the ground are represented by 8-noded solid elements. The infinite elements are used to represent the infinite boundary condition ...

Dynamic response analysis of single-span guideway caused by high speed maglev train

High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of three vehicles and each vehicle is r...

Dynamic Analysis of Asymmetric Structures Supported by a Sliding Foundation

Dynamic Analysis of Hyperestatic Structures under High Speed Train Loads

The construction of new high speed railway infrastructure in many European countries is actually a great civil engineering effort. One of the main design issues is related to the fact that trains at speeds above 220 km/h may induce resonance effects in structures as bridges, subway frames, etc. In consequence, the design of such structures requires dynamic calculations. Several methods are avai...
