摘要
提出利用小波变换的多分辨率特性 ,对安装在飞机机翼上的应变传感器的实测数据进行分析 ,得出其频率特性。并将该方法与传统快速傅立叶变换分析结果进行比较 ,探讨了使用小波变换对工程实测数据进行分析的可行性。
The wavelet transformation method is used to analyze the characteristics of measure data.The data were obtained from the sensors installed on the wings of the flying airplane.The frequency characteris tics resulted is given out.The method is compared to the traditional FFT(Fast Fourier Transformation)analysis.The feasibility of analyzing the engineering measure data using wavelet transformation is discussed in this paper.
