【Abstract】In this paper，based on the electromagnetic field produced by the wire beam induced by the current of the wire beam，the simulation of the emission of low frequency electromagnetic radiation is carried out，the problem of whether the near-field observation point can replace the actual receiving antenna to simplify the simulation process and the modeling method of the wire harness，the simulation models of the actual receiving antenna and the near-field point are established by the simulation software to evaluate and analyze the electromagnetic field.

【Key words】electromagnetic radiation emission；receiving antenna；near-field observation point；wire harness modeling
