摘　　要：分析了雷电的产生机理并对雷电回击电流模型进行简化,建立复杂程度合适的汽车模型,模拟雷电作用下汽车内的电磁环境,得到汽车重要位置的电磁场强度曲线。模拟结果表明:在雷电离车距离较近时,产生的电磁场强度远远大于参考值,这为汽车的电磁兼容设计提供了参考依据。The generation mechanism of lightning was analyzed and the model of the lightning return-stroke current was simplified. Then a vehicle model of suitable complexity was constructed. The electromagnetic environment in the vehicle under the condition of lightning was simulated and the electromagnetic field intensities of some important parts were obtained. The result, which suggests that the electromagnetic field intensity is far bigger than the reference value when the lightning is near, provides a reference for EMC design of the vehicle.
