摘要：
This paper examines the dynamic electroelastic response of Rosen-type piezoelectric transformers in a combined experimental and numerical investigation. Experiments were performed to measure the electrical impedance and voltage gain at various frequencies. The finite element method was also used to solve the coupled electro-elastic boundary value problem. The electrical impedance and voltage gain were calculated and a comparison was made between experiment and simulation. The effects of load resistance and capacitance on the voltage gain and electroelastic field concentrations were also discussed.
