摘要

针对飞机金属结构广布疲劳损伤的检测需求

介绍了一种柔性矩形涡流阵列传感器

通过有限元模型分析了其裂纹响应特性

并搭建模拟裂纹检测系统。通过试验研究了传感器的裂纹检测特性

优化了裂纹检测频率。研究表明:当裂纹"扩展"进入感应线圈的检测范围时

输出信号的幅值开始快速增加

若以各感应线圈幅值信号开始快速增加的"拐点"作为特征量

就可实现裂纹长度的定量检测;当归一化激励频率为0.3时

传感器的裂纹检测能力达到最优。

Abstract

Considering the inspecting requirement of widespread cracks in aircraft metallic structures

a flexible rectangle eddy current array sensor is introduced

and response characteristics of cracks is analyzed by finite element model

and a crack inspecting system which can simulate different cracks is established. The crack inspecting capability is researched and optimize crack inspecting frequency. Research show that amplitude of output signal of sensor will increase greatly as crack propagating into the inspecting region of sensing coil. If the point where the amplitude begin to increase greatly is regard as the characteristic quantity

the sensor is able to inspect cracks quantificationally; and when the normalized exciting frequency is 0. 3

the sensor will have the maximum crack inspecting capability.
