According to the current automotive EMC test stabdard, methods and test status in China, the basic theoretical model of EMC numerical simulation is presented in this paper, and based on simulation software CST, an automotive controller wire harness simulation and analysis model is established. The distribution of electromagnetic field around the wire harness has been studied with the simulation model. With the help of simulation model, the effect of shielding, filtering and reliable grounding on controller EMC property has been studied. It is proposed in this paper to suppress current oscillation in the wire harness to effectively reduce radiation electric field intensity. With the application of this EM field numerical simulation technology, the shortcomings of traditional test method such as prolonged test cycle and overhigh expense are eliminated.
