摘要
根据实测得到的某型飞机典型结构温、湿度数据,采用模糊聚类方法对飞机结构类型进行归并分析,当模糊矩阵阈值λ=0.7时,飞机结构可归并为开式、半开式、封闭式3类典型结构。选取典型开式结构,使用回归法建立开式结构温、湿度预测模型,根据预测模型计算结果对某机场环境谱进行修正计算,编制开式结构局部环境谱,得到的局部环境谱较机场环境谱潮湿空气作用时间比例增加了1.78%。
Lots of local climate environment data of temperature and relative humidity in ground service were obtained by actual measurement, and based on these data, fuzzy cluster analysis was applied to simplify aircraft structure types. When λ = 0.7, the clustering result was that aircraft structure has 3 types, which were open, half open, and close. The open type was chosen as example and the liner regression method was applied to establish the forecast model of temperature and humidity of the typical cabin. The obtained model was applied to modify the airport environment spectrum to get the typical structure local environment spectrum. The calculation result showed that the proportion of humidity climate type in local environmental spectrum increases 1.78% to the airport environment spectrum.
