摘要
针对飞机液压系统的钛合金管缺陷的检测需求,提出了一种外穿式钛合金管阵列涡流检测方法。首先,建立三维仿真模型,分析探头激励频率和激励线圈宽度对缺陷检测信号影响规律。接着,研究了钛合金管内、外壁裂纹的宽度和深度对检测信号的影响规律。最后,制作探头实物和缺陷试件,搭建了钛合金管外穿式阵列涡流检测实验系统,并对钛合金管不同宽度的外壁裂纹和不同深度的内壁裂纹进行实验测试。实验结果表明:本文提出的钛合金管外穿式阵列涡流方法,能够有效检出直径14.0 mm、壁厚2.0 mm的钛合金管外壁长×宽×深为6.0 mm×0.5 mm×0.5 mm的裂纹缺陷和内壁长×宽×深为10 mm×0.5 mm×0.5 mm裂纹缺陷。本文研究结果能够为钛合金管内、外壁裂纹缺陷的检测提供理论基础和方法支撑。
Aiming at the demand for defect detection of titanium alloy tubes in aircraft hydraulic systems,a method for eddy current testing of externally penetrating titanium alloy tube arrays is proposed.Firstly,a three-dimensional simulation model is established to analyze the influence rule of probe excitation frequency and excitation coil width on defect detection signals.Next,the influence rule of the width and depth of cracks of the inner and outer walls of titanium alloy pipes on the detection signal is studied.Finally,the physical probe and defective specimens are made,and the titanium alloy tube external penetration array eddy current experimental system is built.Experimental tests are conducted on the outer wall cracks of different widths and inner wall cracks of different depths of titanium alloy tubes using this system.The experimental results show that the proposed eddy current method can effectively detect crack defects in titanium alloy pipes with a diameter of 14.0 mm and a wall thickness of 2.0mm,the length×width×depth of the outer wall crack defect is 6.0mm×0.5mm×0.5mm,while the length×width×depth of the inner wall crack defect is 10 mm×0.5 mm×0.5 mm.The research results of the paper can provide theoretical basis and methodological support for the detection of cracks defects on the inner and outer walls of titanium alloy pipes.
