V.L.Karlash On comparison of the experimental and calculation data at studying the induced vibrations of piezoceramic resonators |
Acoustic bulletin, Vol. 17 ¹ 3, (2015) |
| The paper deals with comparing of calculated active and reactive components of the full admittance for several piezoceramic resonators with the experimental analogues. The mentioned resonators differ with their shapes, vibration modes and mechanical qualities. For comparison the graphs of calculated and measured curves are plotted in the same coordinate grid. It is shown that the general trends of both curves are similar, and mutual discrepancy may be as much as a few to tens percent. |
