摘要
为了分析火箭弹电磁环境中的响应特性,利用ANSYS HFSS电磁仿真软件,建立了火箭弹发动机及其配用电火工品电磁仿真模型,并在连续波电磁环境中,开展了火箭弹发动机及其配用电火工品电磁环境效应仿真研究。通过探测火工品上的感应电流大小,得到了10×103~18×109Hz频率范围内火工品的频响曲线,以及100MHz时弹内电场分布特点,获得了火箭弹在不同入射方向、不同电场强度电磁场中的耦合规律,为分析火箭弹连续波电磁场中安全性提供支撑。
To analyze the response characteristics of rocket projectile in electromagnetic environment,the electromagnetic simulation models of rocket projectile and electric explosive device(EED)used were built,through ANSYS HFSS electromagnetic soft.The simulation analysis of electromagnetic environment effect on rocket projectile motor and EED were performed in the continuous electromagnetic environment.Through monitoring the induced current of EED,the frequency-response curve of EED was obtained in the frequency range of 10kHz to 18GHz,and the distribution feature of electric field at 100MHz in rocket projectile motor was analyzed,so the coupling role of rocket projectile was gotten with the different strength of electric field and the different direction of polarization.The study can provide support to analyze the safety of rocket projectile in the continuous electromagnetic environment.
