Rail/Axle Gigacycle Fatigue Evaluation Testing

Conventional fatigue strength evaluation of wheel axles and rails based on a 10 order lifespan is not
sufficient in order to guarantee long-term, effective use, improve reliability, and ensure safety. There is an

Ultrasonic fatigue testing machines use a Piezo element to emit a 20 kHz vibration amplification, which is as a result
further amplified using a horn and transmitted to the test sample, realizing a 20 kHz vibration velocity. of inclusion
This contributes to a significant shortening of the time required per test cycle.
