Disclosed is an ultrasonic fatigue testing apparatus. The ultrasonic fatigue testing apparatus of the present invention includes: an electricity generator; an electric-mechanic converter which is connected to one end of a test piece, and which converts the voltage applied by the electricity generator into a mechanical oscillation so as to apply the mechanical oscillation to the test piece; a mechanical-electric converter which is connected to the other end of the test piece, and which converts the mechanical oscillation applied by the test piece into an electric signal; and a controller which calculates data on the fatigue test conducted on the test piece, based on the electric signal transmitted from the mechanical-electric converter. |
