The article uses phased array technology to detect defects on the side of a non threaded cylinder by exciting ultrasonic waves.Firstly,by establishing a three-dimensional model of ultrasonic testing for a non threaded cylinder,simulate the phased array piezoelectric ultrasonic excitation method to generate ultrasonic waves in the three-dimensional model.Afterwards,the waveform of ultrasonic waves inside the non threaded cylinder was analyzed,and defects were set at different positions on the side of the non threaded cylinder.By analyzing the time-domain waveform of the ultrasonic waves,the defect positions on the side of the non threaded cylinder were identified and judged.
