静电引信探测的主要影响因素分析

文章采用电磁场数值仿真的方法对影响静电引信探测的主要因素进行了分析。首先,在导弹壳体不存在的理想情况下验证了仿真模型的准确性;然后,分析了导弹壳体存在时,导弹壳体对探测结果的影响以及壳体带电、海/地平面对探测结果的影响。仿真结果表明,导弹壳体会导致电极板上的感应电荷和感应电流比理论值大,而壳体带电、海/地平面对探测电流基本没有影响。

Analysis of Main Influence Factors on Electrostatic Fuse Detection

To analyze main influence factors on electrostatic fuse, electromagnetic simulation method was first applied tobuild simulation model under the perfect condition without missile shell and the result was in accordance with theoreticalanalysis. Then, influence of the missile shell, the shell voltage and the sea or ground level to detection result was analyzed.Simulation results show that, the missile shell will make the induced charge and induced current larger than the theoreticalvalue, but the shell voltage and the sea or ground level has almost no influence to the induced current.
