摘要复合材料在飞机上的大量应用,可有效提高飞机的整体运营效率。针对飞机复合材料的结构损伤无法准确诊断的难题,提出了一种应用于飞机复合材料结构损伤诊断的方法。首先采用小波能量谱方法对获取到的复合材料结构损伤试验数据进行特征提取,获取损伤信号的特征值;其次,采用基于统计分析的特征值分析,对得到的小波能量谱特征值进行统计分析,得到小波能量谱的协方差信号;最后,依据得到的协方差信号,采用信息熵的方法完成对复合材料结构损伤的诊断。以获取到的某型复合材料结构损伤数据进行试验验证,结果表明,该方法能够实现对复合材料结构损伤的诊断,具有一定的可靠性。

Abstract: The large number of applications of composite materials on aircraft can effectively improve the overall operational efficiency of the aircraft. Aiming at the problem that the structural damage of aircraft composites can not be accurately diagnosed, a method for structural damage diagnosis of aircraft composites was proposed. Firstly, the method of acquiring wavelet energy spectrum was used to extract the wavelet energy spectrum of the collected composite structure damage test data, and obtain the wavelet energy spectrum of the damage signal. Secondly, the statistical analysis was used to statistically analyze the extracted wavelet energy spectrum. The covariance signal of the wavelet energy spectrum was obtained. Finally, based on the obtained covariance signal, the information entropy method was used to diagnose the structural damage of the composite. The experimental results of the damage data of a certain composite material were obtained. The results show that the method can diagnose the damage of composite structures and has certain reliability.

Key words: wavelet energy spectrum information entropy composite material structural damage diagnosis
