摘　　要：本文在线束电流驱动线束感应产生电磁场的基础上,针对低频电磁辐射发射仿真过程中,近场观测点是否能够替代实际接收天线简化仿真流程以及线束建模方式的问题,通过仿真软件建立3种不同线束建模方式下实际接收天线和近场点两种求解电磁场方法的仿真模型来进行评估分析。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.

关 键 词：电磁辐射发射 接收天线 近场观测点 线束建模方式
