摘要
为详细研究UWB(超宽带)、HEMP(核电磁脉冲)作用下长线缆的场线耦合效应问题,并将二者进行比较,依据场线耦合效应计算的Agrawal、Vance模型,推导了能有效用于场线耦合效应编程计算的实用算式。在此基础上编写了Matlab计算程序,对UWB和HEMP作用下长线缆的场线耦合效应进行了计算、分析和比较,得出了两种强场作用下的效应规律。计算显示,UWB和HEMP都能在线缆上激励较高的电流脉冲,也能在线缆端部激励较强的干扰电压脉冲;在相近条件下,UWB激励的响应弱于HEMP;二者相比,其场线耦合效应既有相似之处,又有不同的特点。
In order to study the problem of field-wire coupling effects for long wire in UWB and HEMP in detail,and to contrast the field-wire coupling effects in HEMP with UWB,this paper deduces an applied formula which can apply to calculation by program effectively according to Agrawal and Vance models.The paper writes a Matalb program based on the formula,and applies the program to calculate field-wire coupling effects in UWB and HEMP.It gets the rule of the two intense electromagnetic fields.The result show that both UWB and HEMP can drive high current pulse on wire,and can drive intensity voltage pulse at end of wire;the response of UWB is weak to the response of HEMP at similar conductions.The field-wire coupling effects of UWB and HEMP have some similarities,and also have some different characteristic.
