Ultrasonic Beam Profile Characteristics for Surface Defect Detection in Mobility Components

Nondestructive ultrasonic technology has garnered significant interest from various industries, including agriculture, medical engineering, and airport security. In general, microcracks formed during the machining of mobility components not only degrade performance but also reduce overall quality. Therefore, appropriate nondestructive techniques are required to ensure the reliability of mobility components. Rayleigh waves were utilized for surface monitoring of the mobility parts, and ultrasonic beam radiation measurements were performed to predict beam profile behavior. A contact-type measurement jig was used to measure surface defect reflections. Furthermore, Rayleigh wave generation and optimal testing conditions were realized through CIVA simulation, which provided insights into ultrasonic behavior under controlled conditions.
