【摘要】 本文针对高功率电磁脉冲作用下整车关键敏感设备电磁耦合问题,通过整车电磁脉冲耦合机理及耦合路径的分析,建立了整车关键敏感设备电磁脉冲耦合仿真模型。利用商业电磁仿真CST,仿真得到了耦合路径上不同接地位置处设备端口电磁脉冲耦合大小。给出了电磁脉冲作用下驾驶舱接地(0.5Ω)和控制器接地点(0.01Ω)耦合干扰对比仿真结果,仿真结果表明:接地阻抗越大,电磁耦合电压就越大。在工程应用过程中,应使接地良好。更多还原

【Abstract】 This paper focuses on the electromagnetic coupling problem of vehicle key sensitive equipment under the action of high power electromagnetic pulse(HPEMP).The electromagnetic pulse coupling simulation model of the sensitive equipment is established by analyzing the mechanism and coupling path in the vehicle.By using commercial electromagnetic simulation CST,the coupling of the device port at different grounding positions along the coupling path is obtained.Compared with the simulation results of cockpit grounding impedance with 0.5Ω and controller grounding impedance with 0.01Ωcoupling interference,it can be concluded that the greater the grounding impedance,the more serious the electromagnetic coupling phenonmenon.In the process of engineering application,the grounding should be good.更多还原
