摘要: 超声无损检测方法具有缺陷定位较准确、对面积型缺陷检出率较高、灵敏度高等优势，可对较大厚度构件的内部缺陷进行无损检测。本文针对厚壁复合压力容器的超声检测方法，基于LabVIEW编程语言开发了多通道超声检测软件系统，提出了适用于超声波的时频信号处理的连续小波变换，实现了厚壁复合压力容器超声检测结果的自动化分析。
Abstract: Ultrasonic non-destructive testing method has the advantages of accurate defect location, high effectivity to area defects and high sensitivity, especially, it can detect the internal defects of thicker structures. In this paper, a multi-channel ultrasonic detection software system is developed by LabVIEW for thick-walled composite pressure vessel. The continuous wavelet transform is intro-duced to process the ultrosonic signals for a better time-frequency analysis, and the software sys-tem can achieve an automatic detection results for thick-walled composite pressure vessel.
