Changes of Vibrational characteristics due to the spaces of the Langevin type vibrators

초록
Bolt-tightened Langevin type vibrators using longitudinal mode of bar were designed and fabricated. In order to amplify the displacement of the tip of the vibrators, stacked ceramics were used and five different shapes of the horns were designed and fabricated. Resonant frequencies and vibrational characteristics of vibrators and horns were analyzed by ANSYS(finite element analysis computer program), and the displacements of tips of the horns were measured. As results, when the number of the stacked ceramics were increased, the displacements of the tips were increased and the driving voltages were decreased. Step1 horn(BLT-Stl) showed maximum displacement of 36.92[
