多模态超声导波管道检测技术的研究

目前管道检测技术尚难实现大面积、长距离和复杂状态管道的早期裂纹快速检测。而多模态超声导波管道检测技术,利用超声导波,基于小波分析、遗传算法和随机理论,研究激励的方法、信号的采集、分析和管道状态判别的理论和技术,可以实现这一目标。

By now pipe＇s NDT is difficult to detect crack in great area,long and complex state pipe. Multi--modes ultrasonic guided waves in pipe＇s NDT can realize this object,by using small waves analyse,inheritance arithmetic and random theory to research the means of inspirit,collection and analyse of signal,theory and technology to distinguish pipe state.
