摘　　要：在超声检测时需要通过大量的实验才能实现缺陷的定量,确定合适的检测方案。通过建立基于多元高斯声束的探头发射声场模型,研究不同探头发射频率、探头尺寸、探头类型及不同界面下探头发射声场的分布规律,得出各检测参数对探头发射声场的影响,从而为确定合适的探伤方案提供一定的理论指导;基于建立的探头发射声场模型,结合波恩近似算法,建立夹杂类缺陷回波模型,并且通过实验验证了该模型的有效性,为夹杂类缺陷的定量分析提供了一定的理论指导。In the ultrasonic detection to quantitative through a great deal of experiment to realize the defect,determine the appropriate detection scheme.Through the establishment of sound field model of multiple beam transmission Gauss probe based on the probe of different probe emission frequency,size,distribution of probe types and different interface dropping hair shot sound field,the effects of parameters on the detection the probe field emission,so as to provide some theoretical guidance for determining the appropriate inspection plan;sound field model based on the combination of probe emission,Bonn approximation algorithm,the establishment of inclusion defects echo model,and the validity of the model was verified through experiments,provides a theoretical basis for the quantitative analysis of inclusion defects.
