利用2通道声发射分析仪对钻井吊环的拉伸试验进行动态监控与缺陷定位。试验证明,这种分析仪抗干扰能力很强,可在结构受力条件下进行监控,发现发展中的缺陷,并判定缺陷的位置。
Dynamic monitoring and defect location of drilling rigging tension test using 2-channel acoustic emission analyzer. Experiments show that this analyzer has a strong anti-interference ability, which can be monitored under structural stress conditions to find defects in development and to determine the location of defects.
