Simulation Analysis of Crosstalk of Complex Cable Beams in High Speed EMUs

Abstract

Based on the cable transmission line simulation method, crosstalk simulation analysis is performed on complex cable harnesses commonly used in high-speed EMUs such as power cables, DC power cables, communication cables and signal cables. Through the simulation operation, the waveform and amplitude of the crosstalk signal on the victim cable under different types of interference cables are analyzed. It is concluded that the crosstalk of the power cable to other types of cables is particularly obvious. By changing the parameters of interference signal frequency, cable spacing and cable length, the influence of the above parameters on the crosstalk of complex cable bundles is studied. The research results of cable crosstalk are analyzed and summarized, which can be used for wiring and design of complex cables in practical engineering.
