| Abstract: | Methods for measuring the resonat frequency and the angle amplification ratio of torsional transformers are introduced in which a small-signal sine electromagnetic excitation or an impulsive mechanical knock excitation is used to excite the horn and accleromoters are used to measure the response signals. The methods have used in experimental studies. |

| Keywords: | Ultrasonic torsional transformers resonat parameter measurement sine electromagnetic excitation impulsive machnaical knock excitation |
