Abstract

Abstract: To analyze change rules of train shunt-circuit current amplitude envelope under the track circuit crack state, a distributed parameter equivalent mathematic model of ZPW-2000A track circuit crack state was constructed based on the transmission theory; and the effect of ballast resistances, the crack points and the crack equivalent impedances on train shunt-circuit currents amplitude envelope were studied using MATLAB. Experiment results show that the ballast resistance, the crack point and the crack equivalent impedance have great influence on train shunt-circuit current amplitude envelope before crack point; and the train shunt-circuit current amplitude envelope occurs discontinuity at the crack point regardless of any case. This mathematic model provides a new thought and theoretical basis for testing crack of rail line.
