摘要: 基于并行时域有限差分（FDTD）方法，以大型分裂型分布式负载垂直极化EMP模拟器有效工作空间的选择为目的，先对固定尺寸的该类型模拟器不同平面上的电场垂直分量峰值（简称为“场峰值”）分布特性进行了研究，进而给出了该类型模拟器有效工作空间的选择方法示例；并据此选择了影响该类型模拟器有效工作空间尺寸的两个典型平面为监测面，研究分析了模拟器的最大宽度、模拟器的架高、及模拟器上极板空隙最大尺寸对所选择的监测面上（归一化）场峰值分布的影响，进而给出模拟器的设计建议。模拟结果表明：模拟器的最大宽度越宽、模拟器的架高越低、及模拟器上极板空隙最大尺寸越小，会使得所选择的监测面上场峰值有增加的趋势；模拟器最大宽度的增加会使得场峰值在模拟器宽度方向上的均匀性变好；模拟器架高的增加会使得场峰值在模拟器高度方向上的均匀性变好，但会使得在宽度方向上的均匀性变得略差；模拟器上极板空隙最大尺寸的增加会使得模拟器内场峰值在宽度方向上的均匀性变好，但会使得其在高度方向的均匀性变差。Abstract:
Background There is currently little research on the choice of the effective work-space of large split vertically polarized electromagnetic pulse (EMP) simulator with distributed terminator.Purpose In order to get the distribution characteristics of the peak-value of electric field’s vertical component (called “field peak-value”) inside large simulators,Methods two typical planes were chosen as testing-planes found on an example of selecting the effective working-space of this type of simulator firstly, then the influences of the maximum width, the maximum height, and the maximum width of the upper plate’s void on (normalized) field peak-value distribution characteristics on the two testing-planes, are studied and analyzed based on parallel finite-difference time-domain (FDTD) method.Results The results show that, field peak-values increase on the two testing-planes, as the simulator’s maximum width is wider, maximum height is lower, and maximum width of the upper plate’s void is smaller. The field peak-value uniform along the simulator’s width direction becomes better as the simulator’s maximum width increases; The field peak-value uniform along the simulator’s height direction becomes better, but becomes slightly wrong along the simulator’s width direction, as the simulator’s maximum height increases; The field peak-value uniform along the simulator’s width direction becomes better, but becomes wrong along the simulator’s height direction, as the maximum width of the upper plate’s void increases.Conclusions When selecting an effective workspace in practical experiments, it is necessary to select the appropriate size-parameters of the simulator according to the field peak-values required by the effect experiment and the actual size of the effector, combined with the engineering practice.-
