N2 - In order to quantify the influence of the angle between the axis of the sound beam and the crack orientation on the detection reliability during the ultrasonic testing, this paper uses COMSOL Multiphysics to simulate the numerical simulation of ultrasonic testing and explores the variation of the ultrasonic detection amplitude with the angle. The function of fitting the function is given, and then the numerical simulation method of ultrasonic detection reliability considering the influence of the angle between the beam axis and the crack orientation is proposed. According to the numerical simulation case of ultrasonic detection reliability, the following conclusions are obtained. When the detecting device detects a crack of less than 2.23 mm and the detection probability is greater than 90%, the angle between the axis of the sound beam emitted by the detecting device and the direction of the crack must be greater than 70 If the detecting device detects a crack greater than 0.7 mm and the angle is greater than 86, the probability of detecting the crack is greater than 61.35%.
