本文研究目的為探討一塊壓電三明治Mindlin Plate的動態響應，此三明治板結構的上下層為鋁合金板，中間為壓電材料(PZT-5H)。
　　本文經由Mindlin Plate理論，計算出結構的應力、應變，再藉由應力、應變推算出動能及應變能方程式。通過邊界條件以及形狀函數計算出運動方程式，再以Hamilton’s Principle 理論計算出壓電三明治之統馭方程式，應用解析法於求出壓電複合板之模態頻率。
　　施加一個集中型移動負載於結構上，獲得其位移與電壓，並探討改變移動負載的速度對於位移與電壓的影響。

The purpose of this paper is to investigate the dynamic response of a piezoelectric sandwich Mindlin Plate. The upper and lower layers of the sandwich plate structure are aluminum alloy plates with piezoelectric material (PZT-5H) in the middle.
The stresses and strains of the structure in this paper are calculated via the Mindlin plate theory. The kinetic energy and strain energy are derived by stress and strain. The governing equations of the piezoelectric sandwich plate are derived by Performing Hamilton's Principle. The modal frequencies of the piezoelectric composite plate are obtained by analytic method.
Applying a concentrated moving load on the structure obtain the displacement of the plate and the voltage on the piezoelectric layer. The velocity effect on the displacement and voltage is investigated in the thesis.
