The working principle of pulsed eddy current ( pec ) nondestructive testing technology is analyzed, the pec testing system was been established to examined the specimen of multi - layered aircraft structure, peak and zero - crossing time of the time domain transient response signal of pec are extracted as the features to detect the corrosion in the second layer of aircraft structure quantificationally, the experiment results are consistent with that of the theory analysis, as the pec have the advantages of fast speed and quantification, this makes the method have the broad using foreground in the testing of aircraft structure corrosion
摘要對脈沖渦流無損檢測技術的工作原理進行了分析，建立了脈沖渦流的檢測系統對加工的模擬飛機多層結構的試件進行了測試，提取其時域瞬態感應信號的峰值和過零時間作為特徵量，對出現在飛機多層結構第二層中的腐蝕缺陷進行了定量檢測，試驗結果和理論分析相一致，證明了脈沖渦流檢測方法的有效性，由於其具有快速和定量化的優點因而在飛機結構的腐蝕檢測中具有廣闊的應用前景。Testing result showed that inspecting corrosion situation of oil storage tank bottom in eddy current testing was possible, he quality and improvement of probe affected the trial result greatly
