摘要
使用压电方程结合梁弯曲公式和有限元仿真的方法建立了三叠片式压电加速度传感器的数学模型,通过实验验证了模型的正确性.对三叠片式压电加速度传感器的结构进行了优化设计,在不改变传感器几何轮廓的基础上提高了传感器的灵敏度,并定量分析了不同的结构对传感器性能的影响.提出了三叠片式压电加速度传感器在矢量水听器中的应用方案,使用有限元法对矢量水听器进行了分析计算,制作了矢量水听器样品,并对其主要性能进行了测试.
The sensitivity equation of the bimorph type piezoelectric acceleration sensor was derived from the piezoelectric constitutive equation and the bending formula of cantilever,the finite element method was also used to build the model of the sensor. A method of improving the performance of the acceleration sensor by fabricating hollow structure on surfaces of the metal beam part was analyzed by using finite element method. A vector hydrophone by using bimorph type acceleration sensors was designed,modeled and tested.
