Application Cases

Experiment Name: Performance Measurement of Radial-Torsional Vibration Conversion Ultrasonic Transducer

Experimental Principle:
The transducer is driven by a signal generator and a power amplifier. A laser vibrometer is used to non-contact measure its vibration amplitude at different frequencies, thereby determining the resonant frequency of the system. This also verifies whether the radial and circumferential vibration outputs meet theoretical and simulation expectations, thus evaluating the actual performance of the ultrasonic torsional vibration transducer.

Experimental Procedure:
First, the optimal parameter slant-groove disk and magnetostrictive drive assembly were machined and assembled. Through circuit matching and frequency sweeping, the system resonance point was precisely determined to be 9.83 kHz. Subsequently, a laser vibrometer was used to measure the radial and circumferential amplitudes of the disk, confirming that the conversion ratio was consistent with simulations. Finally, the complete transducer was tested, yielding a torsional amplitude of 4.7 μm at the output end. This verified that the design effectively achieves the conversion and output from radial vibration to torsional vibration.
