以奥氏体不锈钢为研究对象,针对现有超声相控阵技术,用仿真软件建立了大小为50 mm×50 mm的声源平面.在声源平面上建立了超声相控阵声场的可视化仿真模型,仿真了中心频率为5 MHz,阵元数为16的线性阵列换能器,按照TFM算法要求的规则采集回波信号并成像,并与现有超声相控阵成像结果进行系统地比较,发现TFM可以更准确地获得缺陷的位置信息,将TFM应用于超声相控阵检测,可以获得较好的缺陷检测效果. Taking austenitic stainless steel as the research object, aiming at the existing ultrasonic phased array technology, a sound source plane with the size of 50 mm × 50 mm was established by using the simulation software. The visual simulation of the sound field of the phased array ultrasonic phason was established on the sound source plane Model, a linear array transducer with a center frequency of 5 MHz and an array element number of 16 was simulated, echo signals were acquired and imaged according to the rules required by the TFM algorithm, and compared with the existing ultrasonic phased array imaging results systematically, It is found that the TFM can obtain the location information of the defect more accurately and the TFM can be applied to the ultrasonic phased array detection to obtain the better defect detection effect.
