Abstract:Based on the piezoelectric constitutive equation, the finite element model of coupled-field of PZT-Si₃N₄ film is established. Static analysis and first order modal simulation on the PZT-Si₃N₄ film are accomplished by using ANSYS software. The actuation capability of ring film is compared with that of circular film. The influences of structural parameters of actuation film such as thickness and diametrical ratio on actuatting deflection are analyzed separatedly. The optimum bonding ratio of PZT/Si₃N₄ is obtained.
