巴克豪森检测法航空安全应用深度解析

In-depth Analysis of Application of Barkhausen Noise Inspection to Aviation Safety

伴随制造工艺与材料的进步,现代飞机的可靠性得到极大提高,但航空器如果运营操作不当或者维护修理不当,导致零件材料发生过热损伤、性能下降,甚至断裂、失效的事故仍然时有报道;寻找一种既可靠又简便的在翼过热检测手段来排除隐患显得尤为重要;文章剖析了铁磁材料热损伤与残余应力及其磁性变异三者之间的内在相关性,并结合航空维修企业MRO生产实践,指出巴克豪森检测法是一种排除航空零部件过热损伤的可靠方法和有效手段。

Along with the advancement of manufacturing processes and materials,the reliability of modern aircraft has been greatly improved.However,if the aircraft is not properly operated,maintained or repaired,troubles on component materials such as overheating damage,performance degradation,or even fracture and failure will still appear occasionally.It is particularly important to find a reliable and simple on-wing detection method of overheating to eliminate hidden risks.The article analyzes the internal correlation among thermal damage of ferromagnetic materials,residual stress and magnetic variation.Based on aviation maintenance MRO production practice,it is proposed that the Barkhausen detection method is a reliable and effective method to eliminate overheating damage to aviation components.
