摘要

飞机钛合金结构损伤的监测

对于保证飞行器的安全具有重要的意义。提出了一种涡流阵列传感器

并通过搭建监测系统

进行了TC4钛合金不同宽度裂纹扩展模拟监测实验研究。研究结果表明:当钛合金出现裂纹后

传感器各通道的输出信号与无裂纹的基准信号有较大的变化

并且随着裂纹宽度的增加

输出信号幅值比增大。同时

模拟监测实验研究表明:传感器能够准确地识别和定量监测裂纹

精度达到1mm。

Abstract

Damage monitoring of titanium alloy structure of airplane has important meaning to ensure safety of aircraft.Put forward a kind of eddy current array sensor

study on different width crack of extension simulation monitoring experiment of TC4 titanium alloy are carried out.Research results show that output signal of each channel of sensor condition of TC4 titanium alloy with crack is amplified compared to standard signal under the condition with crack

along with the width of crack increasing

output signal amplitude increases

too.At the same time

simulation monitoring experiment research show that sensor has the ability of correct recognization and quntitive monitoring on crack with precision of 1 mm.
