As widely application of FEA in product design and performance, the finite element method is used to analyze the structure of nebulizers based on the piezoelectriccoupling theory.
Based on the equivalent elasticity method, the plane coupling vibration of a rectangular piezoelectric ceramic plate was studied and the resonant frequency equation was derived out.
