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 ...
متن کاملDynamic 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...
متن کاملCFD Simulation of High-speed Trains: Train-induced Wind Conditions on Trackside Installations
Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
متن کاملEffects of track characteristics on dynamic responses of train-bridge systems
High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
متن کاملStrength Analysis and Experiment of High Speed Railway Gearbox Bracket
Light-weighting of high speed railway equipments has become a major trend, which leads the upgrades of equipments. A new C-shaped bracket has been produced to connect the driving gearbox with the bogie. This paper built a three-dimensions model of a C-shaped bracket, got the maximum and distribution of the stress and deformation under two different working conditions form finite element analysi...
