|
摘要
通过建立系统电磁兼容性安全裕度模型,提出了指标分解与电磁能量耦合预测、设备敏感阈值评估、总体及设备优化设计相结合的安全裕度实现方法。针对设备敏感阈值评估的难点问题,提出设备敏感特性曲线外推、概率分析方法估计、敏感阈值验证等评估方法。分析了军械内部电起爆装置及点火电路的电磁辐射响应特性,应用提出的方法设计了军械电磁兼容性安全裕度实现流程。
With the safety margin model of system EMC established,the realization method of safety margin combining index decomposition with electromagnetic energy coupling prediction,equipment susceptibility threshold evaluation,overall system and equipment optimization design is proposed.Due to the difficulty of equipment susceptibility threshold evaluation,some evaluation methods,such as extrapolation of equipment susceptibility characteristic curve,estimation of probability analysis method and validation of susceptibility threshold,are proposed.The electromagnetic radiation response characteristics of electrically initiated devices and firing circuits inside the ordnance are analyzed,and the realization flow of electromagnetic compatibility safety margin for ordnance is designed by using the proposed method.
