چکیده
Track circuit coding can be realized by Train Control Center in Highspeed Railway to keep the train running safe. This paper looks into the track circuit coding method using expert system, in which the reasoning process of track circuit coding was realized using software simulation with the data of Beijing-Shanghai High Speed Railway. Combined with test cases, the joint debugging is realized and the track circuit coding expert system is assessed. Final simulation results support that this prospecting method is both feasible and effective, which can secure the safety of the track circuit coding information as well.

Acceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...

There are several factors causing fastening systems to deteriorate faster than the designed life. The high repetitive loads from a moving train being one of the main factors, track irregularities, design and installation defects of track components, non-uniform rail support stiffness, unevenness in the rail seat deterioration are some of the factors causing fastenings systems to deteriorate fas...
متن کاملA Study of the Wear Behavior of a Rail Material
The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train. The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...
متن کاملInvestigating on the Effects of Random Irregularities of Railway Track by Half-Bogie Model
The vibrations produced by trains include two parts which are deterministic and random vibrations. Due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. One of the important sources in producing the train vibrations is rail roughness and irregularities. In this paper, responses o...
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...
