The communication link of transponder transmission system is taken as the research object,the analysis method of field co-simulation is adopted,and the model of BTM transponder antenna is built through the full-wave three-dimensional simulation software.Based on the principle of electromagnetic induction,the antenna is matched to make it reach the resonant state,and the performance of the three-dimensional simulation model is verified by the parameters of the simulation antenna.The typical electromagnetic pulse system-level coupling effect simulation of the transponder system model is carried out.Through the interference simulation of lightning,electrostatic and nuclear electromagnetic pulses,the different pulse duration,spectrum distribution and electromagnetic energy generated by different types of pulse interference are explored,as well as the influence degree of the three interference signals on the system transmission.This will lay the foundation for the in-depth study of train control system electromagnetic interference.
