针对SRM复合材料壳体粘接结构脱粘缺陷定量检测问题,建立了基于导波能量泄漏的脱粘检测模型,并利用定距发送/接收超声检测系统对制作的复合材料壳体/绝热层试件进行了检测。实验结果表明:基于导波能量泄漏的脱粘检测模型能有效地对复合材料粘接结构脱粘缺陷进行定量检测,由“能量-位置”曲线(“E-x”曲线)的凸区间范围可以判断脱粘的大小与区域。 Aiming at the problem of quantitative detection of debonding defects in bonded structure of SRM composite shell, a detackification detection model based on energy leakage of guided wave was established. The distance transmission / reception ultrasonic testing system was used to fabricate the composite shell / Pieces were tested. The experimental results show that the debonding detection model based on the guided wave energy leakage can effectively detect the debonding defects of the bonded structure of the composite material. From the convex section of the “energy-position” curve (“Ex” curve) Range can determine the size and area of ​​debonding.
