| Summary: | 碩士 === 國立成功大學 === 工程科學系 === 102 === In this thesis, the cantilevered Timoshenko beam surface mounted with a pair of piezoelectric layer is presented. The finite element method is adopted to analyze the behavior of the entire beam, considering coupling effect of force and voltage.
The shape functions of one element are obtained from solving the equations of static equilibrium. The stiffness matrix and mass matrix of the element are obtained by substituting the shape functions into the stain energy and the kinetic energy. Using a resistor to connect two surfaces of the piezoelectric layer to acts as a passive damper. Results show that the length, location and thickness of the piezoelectric layer play the significant factor on deformation of the entire beam.
