收集百余架某系列民航飞机近十年的腐蚀损伤数据，及其过夜停放的16个基地机场的气象环境指标数据，利用动态聚类分析方法，对基地机场的腐蚀环境区域进行了划分，得到对该系列飞机的腐蚀行为影响规律具有相似性的4类腐蚀环境区域。其次应用方差分析方法，对在不同类型机场环境区域的腐蚀频率进行了差异性研究。结果表明，不同机场环境区域的飞机结构腐蚀频率有显著的差异。研究成果对编制民用机场环境谱和进行腐蚀加速试验选取参数有重要的参考价值。
Based on the corrosion data of a series of aircraft for recent 10 years, meteorological and environmental indicators of aircraft base airports, using dynamic clustering method, the environmental areas of aircraft base airports were divided firstly, and then four types of corrosion environment area for corrosion behavior of this series aircraft were got out with similar affecting laws. Secondly, the corrosion frequency of different types of airport environment was investigated by analysis of variance. The results show that the aircraft corrosion frequency in different airport environments varied as region varied. This research provides an important reference for working out a civil airport environment spectrum and selecting the parameters for the acceleraed corrosion testing.
