摘要
针对海洋气候环境与复杂电磁环境耦合下典型机载电子设备的失效机理及环境适应性评估问题,首先系统剖析了海洋气候环境下典型电子设备的腐蚀失效行为和机理,揭示了大气腐蚀、电偶腐蚀、点蚀等关键腐蚀机制。接着,详细探讨了复杂电磁环境对典型电子设备的影响机制,聚焦电磁脉冲对电子设备的耦合路径研究。同时,深入阐述了腐蚀与电磁的相互作用对电子设备性能的影响,阐明电磁场能够促进或抑制金属腐蚀,且腐蚀会改变电子设备的电磁特性,导致电磁防护性能下降。此外,总结了基于数学统计分析和人工智能驱动的电子设备复杂环境适应性评估方法。为电子设备的腐蚀控制、电磁防护、环境适应性评估提供理论支持。最后,提出了当前尚需解决的问题及未来发展的方向。
The work aims to investigate the failure mechanisms and environmental worthiness assessment of typical airborne electronic equipment under the coupling of marine climatic environments and complex electromagnetic environments.First,the corrosion failure behavior and mechanisms of typical electronic equipment in marine climatic environments were systematically analyzed,revealing key corrosion mechanisms such as atmospheric corrosion,galvanic corrosion,and pitting corrosion.Next,the impact mechanism of complex electromagnetic environments on typical electronic equipment was examined in depth,focusing on the coupling paths of electromagnetic pulses acting on electronic equipment.Meanwhile,the impact of the interaction between corrosion and electromagnetism on the performance of electronic equipment was elucidated,clarifying that electromagnetic fields could either accelerate or inhibit metal corrosion;conversely and the corrosion altered the electromagnetic properties of electronic equipment,leading to reduced electromagnetic protection performance.In addition,the complex environmental worthiness assessment methods for electronic equipment based on statistical analysis and artificial intelligence-driven approaches were summarized.These findings provide theoretical support for corrosion control,electromagnetic protection,and environmental worthiness assessment of electronic equipment.Finally,outstanding issues and future research directions are outlined.
