摘要:
復合板過渡層處缺陷一直是衍射時差法超聲(TOFD)檢測的難點。針對這一問題,通過對TOFD成像原理、TOFD探頭參數的設定、探頭中心距的選擇和上下表面盲區的分析研究,并制作了大量含有人工缺陷的模擬試樣加以比對,以及對大量缺陷圖譜進行了分析。結果表明,采用雙通道兩組探頭,分別聚焦2/3壁厚處與過渡層處,同時增加雙面掃查與偏置掃查,可有效檢出過渡層處的缺陷。
Abstract:
Defects in transition layer of composite plate are always difficult to time of flight diffraction(TOFD) detection. In order to solve this problem, the TOFD imaging principle, the setting of TOFD probe parameters, the selection of probe center distance and the analysis of the upper and lower surface blind zone were studied. A large number of simulated samples with the artificial defects were compared, and a large number of defect maps were analyzed. The results show that the defects in the transition layer can be effectively detected by using the two groups of the dual-channel probes, which focus on 2/3t and transition layer respectively, and adding the double-sided scan and offset scan at the same time.
