摘　　要：本文采用粉末冶金法研制了 PZT系独石型梯度功能压电陶瓷驱动器 .对该驱动器弯曲谐振的固有频率进行了实验研究 ,并由双层复合悬臂梁模型推导了弯曲谐振的固有频率 .A monolithic piezoelectric actuator based on functionally gradient PZT ceramics was prepared by powder metallurgical process. The natural frequencies of bending resonance were studied by experimental and theoretical methods. There is a good agreement between measured and calculated results.
