Development of an ultrasonic fatigue testing system for gigacycle fatigue

Abstract: High cycle fatigue (HCF) in the range of 10 6 to 10 8 cycles and very high cycle fatigue (VHCF) in the range of 10 8 to 10 10 cycles are key design criteria for aerospace, automotive, military, transportation, and other industries. However, data gathering in the HCF and VHCF ranges is inefficient with traditional 50to 100-Hz servo-hydraulic testing machines. The development of high power piezoceramic actuators makes it possible to reliably conduct HCF and VHCF tests within a very short time frame at high frequ… Show more

“…The present authors 30,32 provided design and development details of the ultrasonic fatigue testing system, for example, a power supply/signal generator, piezoelectric converter, horn, booster, test specimen, data acquisition and control systems. Readers can refer to detailed description for design iterations of the acoustic stack and technical aspects of generation, control and verification of vibration amplitudes and representative fatigue data validation in references 30,32 …”
