Simulation Analysis Of Bearing Ring Defect Detection Based on Water-Immersed Focused Ultrasound
In the industry,water immersion focused ultrasonic technology is often used to detect the defects of bearing rings.Factors such as focusing probe frequency,water layer thickness,and defect location will affect the de-tection effect.Therefore,based on the finite element method,simulation research is conducted on such influencing fac-tors to simulate water immersion focused ultrasonic testing of bearing rings under the conditions of different probe fre-quencies,water layer thickness,and defect location.Collecting defect echo signals to analyze their impact on the de-tection effect,it is concluded that the probe frequency should meet the requirements for the minimum size of defects that can be detected,and the water layer thickness should be set to ensure that the detection effect is best when the bottom wave of the bearing is in front of the secondary interface wave and the defect position is in the focus area.
