摘要: 全聚焦相控阵是当前超声无损检测领域的研究热点,但其声场特性和检测工艺方面的研究较少。在CIVA仿真软件平台的基础上,开展了全聚焦相控阵的声场仿真计算与缺陷响应研究。采用相同激发参数和孔径的超声探头仿真常规超声声场和全聚焦相控阵声场,分析比对各自的声场特性。通过缺陷响应研究模拟全聚焦相控阵声场与横通孔之间的作用,并分析了全聚焦相控阵技术的检测能力。该研究工作有望为全聚焦相控阵探头的研发设计以及检测工艺的制定提供参考。Abstract: Total focusing phased array is a hot topic in ultrasonic nondestructive testing. However, its acoustic characteristics and testing process are rarely reported. Based on the CIVA simulation software platform, the acoustic field simulation and defect response of total focusing phased array are studied in this paper. Using the same excitation parameters and probe aperture to simulate the conventional ultrasonic sound field and the total focusing phased array sound field, the characteristics of each sound field are analyzed and compared. The impact between the sound field and the transverse hole of the total focusing phased array is simulated by the defect response simulation, and the detection ability of the total focusing phased array technique is analyzed. The research work of this paper provides an reference for the R & D design and testing process of total focusing phased array probe.
