Electromagnetic Modeling and Simulation Analysis of Electric Explosive Device

摘要:

以常规结构电火工品为研究对象,在分析电磁环境对火工品作用机理的基础上,采用 ANSYS HFSS电磁仿真软件建立火工品电磁模型,按照 GJB 786-89《预防电磁场对军械危害的一般要求》加载典型电磁能量,从感应射频电流和损耗功率 2个层面,分别研究电磁环境对电火工品的安全性影响,并给出仿真结果。

Abstract:

Taking the conventional structure of EED (electric explosive device) as the research object, based on the analy?sis of the mechanism of electromagnetic environment on EED, the electromagnetic model of EED was established by AN?SYS HFSS electromagnetic simulation software. Typical electromagnetic energy was loaded according to GJB 786-89“Pre? clusion of ordnance hazards in electromagnetic fields, general requirements for”. The security impact of electromagneticenvironment on EED was studied from two aspects of induced radio frequency current and power loss respectively, and thesimulation results was given.
