摘　　要：汽车电磁兼容已经成为汽车设计中必须考虑的问题,导线在汽车电磁兼容问题中占有重要地位,采用数值仿真的方法研究汽车电磁兼容问题有很多优点。讨论了如何建立适用于仿真的汽车模型,对汽车内由于开孔或有连接导线穿过开孔而导致的导线间的串扰,以及车体对导线产生辐射的影响进行了仿真和分析,确定了在选定的车型下合适的天线安装位置,仿真结果有助于加强对汽车电磁兼容问题的研究。The electromagnetic compatibility already becomes the important aspect in automobile design, especially when designing the wires＇ distribution. The numerical simulation method used to study automobile＇s EMC （Electro Magnetic Compatibility） problem has many merits. How to establish the suitable simulation model for automobile was discussed. Through analyzing the coupling between wires due to connected wires or holes, it is known that when the connected wires drill through the holes, the coupling degree between wires is growing rapidly. The automobile body affects the electrical filed inside and outside. To the automobile model and the receiving antenna in 100MHz, the reserved carriage is the proper place to fix the receiving antenna because of less interference.
