摘　　要：强电磁脉冲对车辆电子设备的破坏效应是十分严重的,而电磁屏蔽是有效减少电磁干扰的方法。利用传输线方法(TLM)研究车辆整体在强电磁脉冲(EMP)作用下增加屏蔽材料对电磁屏蔽产生的效果,分析了入射平面波入射方向和极化方向对此电磁环境下屏蔽效能的影响。仿真实验表明车体上增加金属材料屏蔽层对电磁脉冲屏蔽的影响是比较显著的,且电磁脉冲激励源的传播方向和极化方向是影响屏蔽效能的重要因素。The destructive effect of electronic equipment in vehicle is quite serious in high power electromagnetic pulse.The electromagnetic shielding is an effective way to reduce electromagnetic interference.The electromagnetic shielding effectiveness of whole vehicles under the condition of high power electromagnetic pulse （EMP） was analyzed by transmission line method （TLM）.The impact analysis of shielding effectiveness of the incident plane wave direction and polarization direction was given.Simulation results show that adding metal shielding layers on vehicle body has significant effect on the reduction of high power electromagnetic pulse,and the shielding effectiveness is related to incident wave propagation direction and polarization direction.
