Abstract

In this paper, a cylindrical aluminum specimen with an eccentric circular hole is prepared and ultrasonic measurements are carried out by experimental means. The measurement area is restricted to the plane perpendicular to the axis of the cylindrical component. The measured wave data are fed into the approximate correction method formula—the Born inversion procedure—and cross-sectional images are obtained. Next, a 3D shape reconstruction of the defect in the aluminum specimen is performed by stacking the cross-sectional images. After correcting the defect’s echo amplitude, the defect reconstruction effect of the 2D section and 3D defect reconstruction effect improves remarkably.

圆柱构件偏心缺陷形状重建的born -反演方法

本文制备了一个带有偏心圆孔的圆柱形铝试样，并通过实验方法进行了超声波测量。测量区域限制在垂直于圆柱形部件轴线的平面内。测量的波浪数据被输入近似校正方法公式——玻恩反演程序——并获得横截面图像。接下来，通过堆叠截面图像来执行铝样品中缺陷的3D形状重建。对缺陷回波幅度进行校正后，二维剖面的缺陷重建效果和三维缺陷重建效果显著提高。
