压电陶瓷器件因边界条件和应力状况的复杂性而导致传统试验手段对其研究具有一定的局限性,该文针对这一特点,根据压电体结构场和电场的耦合性建立了与试验结果相一致的压电陶瓷有限元模型,利用大型有限元分析软件ADINA经过建立几何模型,定义边界条件,定义材料和耦合计算等步骤系统的分析了典型PZT压电陶瓷在电压作用下的变形问题,证实了模拟结果与真实试验结果的一致性,为实现对压电陶瓷形状和振动的控制奠定基础.

Using traditional experiment means on piezoelectric ceramic device has certain limitations due to the complicated boundary conditions and stress situation.In this paper, the finite element model of piezoelectric ceramics in line with the experiment results was established according to piezoelectric structure field and the coupling of the electric field.Deformation of representative PZT piezoelectric ceramics under the voltage was analyzed using finite element analysis software ADINA according to establishing geometric model,defining boundary conditions and materials, coupling calculation. Consistency between simulation results and experimental results was improved and laid the foundation for the realization of the piezoelectric ceramic shapes and vibration control.
