| Abstract: | IIn this paper,influence of the reinforced concrete structure of the PDL ballastless track on the electromagnetic environment arround the rails is analyzed;the impact of concrete iron magnetic conductivity and distance between track bottom and upper concrete iron on magnetic field distribution is calculated.The effect of change of electromagnetic environment on the cab signalling inductance coil is analyzed.By simulation,the authors get the distribution of magnetic field arround the rails with the consideration of the harmonic wave and noise in the traction return current. |
