| Summary: | 碩士 === 中華大學 === 電機工程學系碩士班 === 91 === The electroelasticity theory consists of the dynamic equilibrium equations, the Cauchy equations, the piezoelectric constitutive equations and electrostatic equations, but the analytical solution is difficult to solve. So ANSYS software is utilized to simulate the static and dynamic behavior of the piezoelectric ceramic motor. We utilize the Harmonic analysis to obtain the resonant frequency of both axes of the piezoelectric component, and we also use the dynamic analysis to get the displacements of both axes. Then we approximate these displacements as mathematic equations related to the frequency of the applied voltage. We can obtain the resonance frequency of x and y axes depend on the some parameters of the piezoelectric ceramic motor.
