Abstract
Ultrasonic phased array technology has been widely used in the field of industrial nondestructive examination (NDE) but how to obtain the ideal results is still lacking. Based on Huygens’ principle, a one-dimensional ultrasonic phased array model was established to study the resultant sound field. Important parameters to the acoustic field characteristics of ultrasonic phased array were systematically investigated, such as the number of array elements, the working frequency, the focal length and the steering angle. Based on the simulation results, the optimal parameters can be obtained which can provide a theoretical basis for the actual application of ultrasonic phased array.
