Research on factors affecting ultrasonic phased array detection imaging quality for curved component

An in-depth analysis on the beam directivity of ultrasonic phased arrays has been made to solve the problems of low image quality and identification difficulties caused by a suboptimal configuration of array elements. The influence on the number and spacing of array elements on the imaging quality of curved components was studied. The simulation and experimental verification of the phased array sound field for curved components were carried out. The rules governing the influence of phased array transducer parameters on imaging quality were obtained, and an approach to the optimization of parameters was proposed. The results of this study have important significance for transducer design and the phased array detection of curved components.
