本文理论上导出了边缘固定金属压电陶瓷双迭片圆板弯曲振动换能器在忽略辐射阻尼和损耗及满足薄板小挠度和轴对称条件下位移的一般解，并进一步得到了共振频率、自由场电压灵敏度的计算公式，和实验样品的测试结果进行了比较。所得结果对金属压电陶瓷双迭片圆板弯曲振动换能器的设计具有参考价值 In this paper, we theoretically deduce the general solution to the displacement of edge-fixed piezoelectric ceramic double-disc circularly-curved vibratory transducers without considering the radiation damping and loss, and meeting the conditions of small deflection and axial symmetry of thin plates, and further obtain the resonance frequency, freedom Field voltage sensitivity of the formula, and the test results of the experimental samples were compared. The obtained results have reference value to the design of bending piezoelectric transducer
