Abstract：With the application of wireless power transfer technology in railway system, electromagnetic safety has attracted more and more attention. In order to effectively evaluate the electromagnetic field of the human body exposed to the high-power catenary-free power supply urban rail transit vehicle, 3d electromagnetic simulation software is used to build the electromagnetic environment model of personnel, and the distribution of magnetic field intensity, electric field intensity and current density of the driver and three passengers (passenger A, B and child) at different positions is studied. The results show that the driver's induced electric field intensity is the lowest, and its induced electric field intensity is 2×105V/m. Passenger A has the maximum induced electric field intensity, which reaches 0.55V/m. The magnetic field intensity at the windscreen connecting the carriage where passenger B is standing is the largest, and its maximum value is 2.78A/m. The maximum induced current density is 13.7μA in passenger B's abdomen. All the calculated results are below the electromagnetic field limits of the International Commission on non-ionizing radiation protection (ICNIRP) guidelines, indicating that both the driver and passengers in the vehicle are safe. Finally, the field measurement data is compared with the numerical calculation results, and the results are in good agreement, which further verifies the correctness of the simulation.
