As communication technology improves and urban rail communication system develops, the new CBTC (Communication-Based Train Control) system built upon train – train(T2T) communication has become the mainstream of future rail transit signaling systems. In the future train-centered CBTC system, Train-to-Ground (T2G Train-to-Ground) mode may coexists with T2T communication mode. To reduce the interference and ensure the reliable transmission of information and system security, a joint channel allocation and power control communication resource distrbution method is proposed, which firstly allocates channels to users by the Hungarian algorithm, and then make use of sparrow search algorithm to coordinates the user’s transmit power. Obtained by simulation results, this suggested strategy not only reduces interferences caused by resource sharing and satisfies the dependability of the system, but also significantly improves the throughput of the system.

The resonance characteristics of a two-span continuous beam traversed by moving high speed trains at a constant velocity is investigated, in which the continuous beam has uniform span length. Each span of the continuous beam is modeled as a Bernoulli-Euler beam and the moving trains are represented as a series of two degrees-of-freedom mass-springdamper systems at the axle locations. A method of modal analysis is proposed in this paper to investigate the vibration of two-span continuous beam. The effects of different influencing parameters, such as the velocities of moving trains, the damping ratios and the span lengths of the beam, on the dynamic response of the continuous beam are examined. The two-span continuous beam has two critical velocities causing two resonance responses, which is different from simple supported beam. The resonance condition of the two-span continuous beam is put forward which depends on the first and second natural frequency of the beam and the moving velocity.

“…The model of guideway has been treated as simply supported Euler-Bernoulli beam by several authors as found in the articles published by Cai et al [2], Ren et al [3], Wang et al [4], Zhao and Zhai [5] and Zheng et al [6]. Teng et al [7] investigated the response of two-span continuous guideway for high-speed magnetic levitation system using moving distributed load without considering the effect of MAGLEV suspension systems.…”

A magnetically levitated (MAGLEV) train is the future of rapid ground transport. They are much faster, energy efficient; require very less maintenance and pollution free. The present study outlines an approach for the modelling and simulation of MAGLEV vehicle-guideway in a block diagram environment and thereafter optimizes the suspension parameters for increased ride comfort. This has been accomplished with the help of SIMULINK which provides a graphical editor, customizable block libraries and solvers. The guideway has been modelled as a twospan continuous beam. The guideway surface roughness was defined by power spectral density function. The influence of vehicle speed and surface roughness on the vehicle-guideway response has been studied. Use of optimized suspension parameters indicated 60 % reduction in car-body vertical acceleration, whereas the guideway maximum deflection showed a fall of 25 %.
