Embodiment Construction
[0026] Next, the present invention will be further described according to the accompanying drawings
[0027] The transducer consists of two sets of ceramic stacks 1, transition rods 2, curved beams 3, transition beams 4, swing columns 5, rigid beams 6, end cover plates 7 and watertight layers 8. The overall length of the transducer in the embodiment is 193mm. Among them, the ceramic stack 1 is made of PZT-4 piezoelectric ceramics; the transition rod 2, the bending beam 3, the transition beam 4, and the swing column 5 are all made of TC4 titanium alloy; the rigid beam 6 and the end cover plate 7 are made of 45# steel, watertight Layer 8 adopts JA-2S polyurethane rubber.
[0028] The ceramic stack 1 is divided into two groups, and each group of ceramic stacks is mechanically bonded in series by eight φ30mm×5mm polarized ceramic sheets and one φ30mm×2mm non-polarized ceramic sheet. The direction of the electrodes of the sheet ceramics is opposite, and the unpolarized ceramic sh...
