“…Phased array ultrasound technology [1,2], originally applied to medical ultrasound and industrial flaw detection, can realize the change in ultrasonic focus and the superimposed deflection of array energy by setting the delay time of the probe, thus enhancing the recognition ability of ultrasonic signals. Aldo et al [3] applied ultrasonic phased arrays to concrete inspection and demonstrated that the technique could detect in a dry coupled state and still identify defects in the presence of reinforcement.…”

Due to the lack of a perfect and convenient method to detect the grouting quality of shield tunnels, an optimized ultrasonic phased array tunnel grouting detection technology is proposed. The particle swarm genetic algorithm is optimized to be used for phased array sparse, and the GA-VMD-SG algorithm is proposed to be used for noise reduction of ultrasonic detection signals, and numerical simulation and experimental methods are used to validate the optimized detection effect of the ultrasonic phased array. The results show that: the GA-PSO algorithm can better simplify the array and reduce the maximum sidelobe value; the GA-VMD-SG algorithm can well reduce the noise of ultrasonic signals; numerical simulation and experiments verify the feasibility of the ultrasonic phased array to detect the quality of grouting and the optimization effect of the two algorithms.

“…By controlling the delay or deflection of sound beams, the acoustic field generated by different array elements interferes, and the acoustic field is focused within the tube wall [8][9][10][11]. The use of ultrasonic full focus to detect internal pipeline corrosion exhibits several advantages compared with using other ultrasonic methods because it can concentrate the energy of the sound beam, increase internal pipeline corrosion detection accuracy, increase detection range by controlling the deflection angle and realize full coverage detection of a pipeline [12][13][14][15]. Ultrasonic full-focus detection has been increasingly studied [16][17][18][19][20][21].…”

Seawater pipelines are an important part of ship structures. After a certain period of service, corrosion becomes a serious problem. Ultrasonic corrosion detection has good applicability in seawater pipeline corrosion detection. Aiming at the focusing problem of ultrasonic arrays in pipeline inspection, the sound pressure characteristics and acoustic field directivity in the propagation process were analyzed. A mathematical model of the acoustic field propagation characteristics was established, and the influence of deflection, focusing of the sound beam, and geometric characteristics of the array element on the characteristics of the ultrasonic acoustic field were analyzed through simulation calculations. An ultrasonic array focusing transducer was used to test the corrosion of a Φ168 pipeline. The results show that the number, size, and focal length of the working array significantly affect the focused acoustic field characteristics of the ultrasonic array. The ultrasonic full-focus method can effectively detect local corrosion of pipelines, and the defect detection accuracy has a nonlinear relationship with the number of working array elements and the focal length of the focus. Within a certain range, with an increase in the number of working elements, the overall tendency of the average error of defect detection gradually decreases. With the increase in focal length, the overall tendency of defect detection error first decreases and then increases, and there is a focal length range with the best detection accuracy. In pipeline inspection, the best working parameters can be selected according to the actual size of the pipeline.
