摘要:
本文建立了有限长薄壳圆管径向振速在若干特定情况下(包括:单振模及多振模)的机电转换等效图。根据单振模径长耦合等效图,得出t《α、L≤2α,ω在ω_L附近频段时圆管径向振速均值的相对频响公式,进而论证了发射灵敏度响应的平坦性。从而从理论上说明了奥岛基良1961年的实验结果。本文的结果可供设计发射型圆管换能器时参考。
Abstract:
This paper proposes the equivalent circuit of the radial velocity in some particular cases, single-vibrating mode and dual-vibrating mode for the thin peizaelectric cylinder. On the basis of equivalent circuit of single-vibrating mode of the radiallongitudinal coupling, the relative response formula of the radial mean velocity of the ring wall has been obtained with t(?)a. L≤2a and near longitudinal resonance frequency. Further, the flatness of the transmitting sensitivity response has been proved. At last, the experimental example, which had already been given in 1961 by Motoroshi Okushima, shows good agreement with the theory of this paper. The result of this paper is applicable to the design of underwaser sound projector of cylindrcal piezoelctric ceramic ceramic ring.
