| 摘 要： | 利用压电方程和小挠度弯振理论,推导了边界自由压电陶瓷双迭片薄板小挠度条件下弯曲振动位移的一般解及振型频率方程。由频率方程计算得到的各阶振型频率与用有限元方法计算的结果基本相符,并基本得到实验结果的验证。所得结论对边界自由双迭片压电振子弯曲振动的设计提供了理论参考。

| Abstract: | A general solution of displacement for piezoelectric ceramic bimorph with free boundary was derived by using the piezoelectric equation and the small deflection bending vibration theory.Resontant frequencies were calculated and verified by the ANSYS numerical results and the experimental results.These results can be referred to the design of piezoelectric ceramic bimorph flexural vibration transducers. |

| Keywords: | piezoelectric ceramic bimorph frequency equation |
