With the continuous development and innovation in field of global magnetic levitation technology, suspended permanent magnet maglev rail transit system has emerged. At present, no mature relevant technical standard references are available world. To study electromagnetic radiation problem train system, we use finite element method to simulate analyze Halbach array track different combinations suspension modules, six-channel high-precision test is used compare actual engineering fields. The results show that can shield energy module beam reduce influence radiation. increase height between vehicle magnets, generated intensity exhibits a significantly weakening trend. maintained at centimeter level. Combined with project, passengers on pedestrians, residents along red not affected by magnet. This paper provides theoretical basis for resolving people’s concerns about trains, important support transit.
