Abstract:
A method of inspecting a rotatable shaft for the presence of defects may include continuously rotating a shaft under an applied load. As the shaft is rotated, an ultrasonic signal may be propagated along the length of the shaft. Attenuated or reflected ultrasonic signals may be collected from the shaft as the shaft is rotated. The presence of a defect in the shaft is determined by analyzing the collected ultrasonic signals.
