碩士 === 國立成功大學 === 工程科學系 === 104 === This study presents the vibration analysis of piezoelectric Mindlin plate under moving load. The host plate is aluminum and the bottom surface bonded with a piezoelectric plate. The governing equations and boundary conditions of the entire system are derived from performing Hamilton’s principle. The finite element method is adopted to analyze the behavior of the entire plate. The shape functions of one element are constructed from solving the equations of static equilibrium. Newmark’s Integration Method is adopted to analyze the plate’s dynamic response. The effects of thickness and area of the piezoelectric layer on the displacement at the center of the plate and the etymology of electricity on the bottom piezoelectric layer are investigated.
