摘要
设计了一种用于地脚螺栓缺陷检测及腐蚀评估的相控阵超声导波换能器,通过对换能器阵列型式、阵元个数、频率、晶片尺寸的合理设计,可以有效避免螺纹反射回波的干扰,提高信噪比和缺陷检测结果的可靠性,并通过检测案例进行了验证。
A phased array ultrasonic guided wave transducer were designed for the defect testing and corrosion wastage evaluation of anchor bolts and other buried anchor bolt systems.By rational designing the transducer array type,number of array elements and frequency and chip size,it is effective in avoiding the interference of thread reflection signals and improving the signal-to-noise ratio and reliability of defect detection results,which has been verified by the experiment.
