摘要：

阻拦索的可靠性及安全性与航母阻拦系统的正常工作和舰载机的安全降落息息相关，因此，加强对阻拦索健康状态监测，进行无损检测研究工作尤为重要。该文基于漏磁无损检测技术，采用永磁磁化方式，设置环状阵列多通道传感器，建立阻拦索检测平台，制作阻拦索在轴向和周向上不同位置断丝和磨损等损伤缺陷，并进行大量检测试验研究。检测结果表明：阻拦索轴向和周向的断丝和磨损缺陷不仅可以明显检测，还可以实现阻拦索轴向和周向缺陷精确定位，其中周向缺陷精度可达30。该研究对提高航母阻拦索的可靠性、安全性以及实现航母阻拦索健康状态定量评估具有参考价值。

Abstract: The reliability and safety of the arresting cables are closely related to normal operation of aircraft carrier arresting system and the safe landing of the carrier-based aircraft. Therefore, it is particularly important to carry out non-destructive testing in order to strengthen the monitoring of health status of arresting cables. Based on MFL(magnetic flux leakage) non-destructive testing technology, a ring array multi-channel sensor had been set up by means of permanent magnet magnetization, and testing detection platform for arresting cables had been built, and the damage defects had been fabricated such as broken wires and wear of arresting cables in the axial and circumferential directions, then lots of experimental study had been conducted. The testing results show that not only the axial and circumferential broken wire and wear defects can be detected, but also those can be located, and the circumferential defect accuracy can be reached 30 degrees. This research has reference value of military and engineering application for improving the reliability and safety of cables and quantitative assessment of health condition.
