Abstract
To fabricate a bolt-clamped large diameter Langevin torsional vibrator as designed is usually difficult. A torsional vibrator tightened with an outside bolt is proposed in which the designed characteristics in the resonant vibration of the normal mode is achieved. A torsional vibrator 80 millimeters in diameter with a calculated resonant frequency of 28 kHz has been fabricated. The resonant frequency of the torsional vibrator is 26.1 kHz, the quality factor is 890 and the maximum angular velocity is 4.1 rad/s. It is confirmed that the vibration characteristics obtained with the externally-bolted transducer are improved compared with the torsional transducer tightened with an inside bolt.
