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。取模糊矩阵阈值为0.7时,飞机结构可归为开式、半开式、封闭式三类典型结构。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,编制了开式结构局部环境谱。
Lots of local climate environment data of temperature and relative humidity in ground service are ob tained by actual measurement, and based on these data, fuzzy cluster analysis ways are adopt to simplify aircraft structure types, when λ = 0. 7, the clustering result is that aircraft structure type is 3 states： open, half open, close. Choose the open type as example ; use the liner regression method to erect the forecast model of temperature and humidity of the typical cabin. And use the obtained model to modify the airport environment spectrum to get the typical structure local environment spectrum. The calculation result shows that the proportion of humidity climate type in local environmental spectrum increases 1.78% to the airport environment spectrum.
