摘要

目的针对铁路高速运输弹药电磁安全不明确问题,准确分析列车内部弹药包装内的电磁环境。方法分别建立高速列车车体、典型弹药包装的电磁屏蔽模型,采用仿真方法分析典型弹药包装材料的屏蔽效能,并进行试验验证,进而对典型弹药包装组合的屏蔽效能进行分析。结果在30 MHz~1.5 GHz,2 mm厚铝金属包装材料屏蔽效能在88 dB以上,而非金属包装材料基本没有屏蔽效能,增加铝塑袋后,屏蔽效能可达55 dB。结论电磁敏感弹药在铁路高速运输时,可采用套铝塑袋、铝包装箱等方式提高屏蔽效能。

Abstract

The work aims to analyze the electromagnetic environment of ammunition packaging inside the train in order to solve the electromagnetic safety problem of ammunition high-speed railway transportation. The electromagnetic shielding models of high-speed train body and typical ammunition packaging were established respectively. The shielding efficiency of typical ammunition packaging materials was analyzed by simulation, and then the shielding efficiency of typical ammunition packaging combination was analyzed by experiments. The results showed that in the frequency range of 30MHz~1.5GHz, the shielding efficiency of 2mm thick aluminum metal packaging materials was more than 88dB, while non-metallic packaging materials had no shielding efficiency, and the shielding efficiency could reach 55dB after adding aluminum plastic bags. In conclusion,the shielding efficiency of electromagnetic sensitive ammunition can be improved by aluminum-plastic bags and aluminum packing boxes when it is transported by railway at high speed.
