摘要
对FRP复合材料容器进行水压爆破的力学性能实验,采集FRP复合材料容器在受压损伤和爆破过程中的声发射信号。基于小波包变换对复合材料容器爆破声发射信号进行时频对比分析,由能量在频段上的分布情况,得出爆破信号特征。
Take the mechanical properties of water pressure blasting experiment of FRP composite container, acquisi- tion of acoustic emission signal of FRP composite material container in compression injury and in the process of blasting. The time-frequency characteristic analysis for composite container blasting emission signals is made based on the wavelet packet transform, by the distribution of energy on the spectrum, blasting signal characteristics is concluded.
