摘要:针对火工品高场强电磁辐射效应考核缺乏试验手段的问题,开展了基于大电流注入法的低频段高场强电磁辐射效应等效测试方法研究,完成等效方法设计。通过辐射效应试验获得耦合规律及辐射场强与火工品响应耦合函数;搭建电磁耦合钳注入试验系统,获得了注入传导耦合规律,建立注入功率与火工品响应关系函数;以火工品的响应参数为中间量,推导建立了辐射场强和注入功率的耦合传递函数,从而在低频段利用注入方法实现对火工品的高场强电磁辐射等效考核。
Abstract:The equivalent test method of low frequency high-field electromagnetic radiation(HEMR) based on bulk current injection was studied for the need of HEMR effect test on EED, and the equivalent test method design was completed. Through the radiation effect experiment and electromagnetic coupling forceps injection experiment research, and by the response function of EED as the middle volume, the coupling transfer function between radiation field strength and injection power was established, so the HEMR equivalent test on EED was achieved in the low frequency range.
