| Abstract(in English) | he self and mutual radiation impedance and mutual radiation power of Langevin type transducers with a bending board on a flat radiation surface are calculated using the farfield method. Numerical results of the mutual radiation impedance are given for an array of 5x5 identical square transducers vibrating uniformly in a common rigid baffle. The directivity of the transducers also is calculated by the same farfield method. According to the calculation result, it is shown that the transducer is not extremely different from characteristics of Langevin transducer. Therefore we can use the conventional method to design a sonar array. And it has the possibility that frequency can be moderated with keeping the same power by controlling the ratio of the piston amplitude and the bending amplitude. |
