| Abstract: | The 2 2 piezocomposite tube with much more elements is analyzed and manufactured in this work. The piezocomposite tube consists of 180 piezoelectric elements which are connected by composite material. The piezocomposite tube has the advantages of large geometrical dimensions, more elements, little interfere between axial vibration and radial vibration, precise facture method and so on. Compared with the pure piezoelectric tube, the 2 2 piezocomposite tube has the characteristic of pure mode in the operating frequency range and suppression of the parasitical modes, and it can be widely used to develop the transmitting array of multi beam imaging sonar. |
