板波对粘接检测的灵敏度的改善

THE SENSITIVITY IM PROVM BNT OF LAM BW AYE FLAW DETECTION IN ADHESIVE COM PONENT

板波被广泛地用于快速地检测大的构件,特别是薄构件中。但板波探伤的灵敏度和分辨率较低。本文提出一种时域加窗提高探伤分辨率的方法,有效地改善了板波对粘接检测的灵敏度。

Lam bwave is widely usedh the high speed ultrasonic flaw detection of Large-sized com ponents,especially of thin com ponents.Butthe sensitisity and resolutionof the detection is no thigh. In this articb, a m ethod of adding w hdow s in tin e doa a in is presented to in prove the resobtion.and thus the adhesive snsitivety is effectively in proved.
