摘要
为有效模拟地面核爆炸源区电磁脉冲电场环境,通过理论分析和PSpice电路仿真确定了模拟器结构尺寸参数,利用CST软件对模拟器辐射场特点进行了仿真模拟;对具体设备进行了设计加工,研制了一套低频宽脉冲电场模拟器,并测试了模拟器的性能指标。结果表明:实测波形与理论和仿真结果具有较好的一致性,研制的模拟器可实现最快上升时间<10 ns、脉宽>1 ms、最高峰值场强100 kV/m、1.6 m×1.6 m×1.6 m (长×宽×高)空间场强不均匀度<10%的辐射场环境。该模拟器的研制为下一步设备效应试验的开展提供了平台。
To simulate the electric field of source region electromagnetic pulse(SREMP) of the nuclear weapon explosion on the ground, through theoretical analysis and PSpice simulation, the structure dimension parameters of the simulator are confirmed. Also, based on the CST software, the radiation field of the simulator is simulated, and then the actual devices are developed. A kind of low-frequency wide-pulse simulator is developed, and the performance indexes of the simulator are measured. The test results show that the tested waveform is well consistent with the theory and simulation results. The simulator can generate a radiation field environment with a rise time shorter than 10 ns, a pulse width wider than 1 ms, the highest field strength 100 kV/m, as well as a lower than 10% asymmetry degree in 1.6 m×1.6 m×1.6 m(length× width×height) space. The development of the simulator provides an experimental platform for further research on equipment effect.
