Quantitative ultrasonic testing for near-surface defects of large ring forgings using feature extraction and GA-SVM

, 2021
Water immersion ultrasonic testing technology is widely used in non-destructive testing of large ring forgings, but near-surface defects are difficult to identify in near-surface blind zone, because the defect echo always overlaps with interface echo. In

Ultrasonic machining of engine lubricating oil during tribotechnical testing

Journal of Friction and Wear, 2017
The results of tribotechnical testing of brass–steel and iron–steel friction couples for both their running-in ability and wear resistance have been described. For brass and iron jaws of friction couples, it has been established that the load before tearing increased to 4.3 and 12.3%, respectively, in synthetic oil, while for semisynthetic oil, it ...

Performance simulation and testing of capacitive micro-machined ultrasonic transducer

Sensor Review, 2019
Purpose This study aims to simulate and test the performance of a transmitting and receiving capacitive micro-machined ultrasonic transducer (CMUT). Aimed at detecting demand of the CMUT, a matched integrated adjustment circuit was designed through analyzing processing methods of transducer’s weak echo signal.
