中文摘要:
      基于超声相控阵基本理论和全聚焦成像算法(Total Focus Method,TFM),以30 mm厚的Q235钢板中的孔缺陷检测为研究对象,使用ABAQUS有限元软件,建立了相控阵TFM有限元检测模型。根据模拟结果,在MATLAB软件中编写了相控阵TFM成像算法。同时,采用超声多通道实验平台,对构建的TFM有限元检测模型和编写的相控阵TFM算法进行实验验证。实验结果与有限元模拟结果有较好的一致性。
英文摘要:
      Based on the theory of ultrasonic phased-array and the total focus method (TFM), the finite element model of phased-array TFM is established by using ABAQUS finite element software for defect detection in a 30mm-thick Q235 steel plate. According to the simulation results, the phased-array TFM imaging algorithm is programmed in MATLAB. The TFM finite element detection model and the phased array TFM algorithm are verified by using ultrasonic multi-channel experimental platform. It is shown that the finite element simulation results are in good agreement with the experimental results.
