V.G.Basovsky Sound radiation by finite grating of open piezoceramic rings |
Acoustic bulletin, Vol. 1 ¹ 2, (1998) |
| The paper deals with considering of the problem on sound radiation by finite gratings of open piezoceramic rings in the case when the preset values on the rings' walls are not the velocities, but input electric voltages. The exact method is offered to solve this problem, allowing for the acoustic field local singularities near the rings' ends. The acoustic interaction of the rings operating in the multielement arrays has been analyzed in the wide range of frequencies and grating spacings. The gratings of two types are studied: ones composed of the pulsing and oscillating rings. |
