中文摘要: 本文针对圆柱体构件超声检测，利用轮廓线法作出了缺陷定位图，通过分析发现了轮廓线法重构圆柱体构件气孔缺陷误差产生是受定位偏角的影响，并用PZFlex超声有限元软件仿真了缺陷回波信号，验证了实验结论，并分析了缺陷位置、大小和信号衰减对定位偏角的影响，为进一步缺陷边界重构奠定了基础.
Abstract:This paper makes defect location maps for cylinder component ultrasonic testing by using Contour Method and finds that the generation of error of Contour Method for porosity defects reconstruction in cylindrical member is affected by the positioning angle. The experimental results are verified with flaw echo signal which is simulated by finite element software of PZFlex. The influence of the defect location, size and signal attenuation for the positioning angle is analyzed, which lays a foundation for further defect boundary reconstruction.
