摘要
利用小波分析的方法以及聚类分析的方法,从重构声发射监测信号的幅值特点入手,找到了一种表征疲劳裂纹发展的方法。以参数统计方法作为参考,通过对飞机结构地面疲劳试验声发射数据的分析,对方法进行了验证。
By using the method of wavelet analysis and the method of cluster analysis,a new method is developed to characterize the fatigue crack growth. Based on the traditional parameter analysis method,the method is verified by the analysis of the ground fatigue test data of the aircraft structure.
