Simulation of Discharge Characteristics of Ferroelectric Ceramics Transducer Based on Simulink

摘要：

　　To analyze the depolarization and discharge effect of ferroelectric ceramics,the physical model of ferroelectric ceramics depolarized by the vertical shock wave is established.Equivalent circuit of the depolarization is built.The mechanical structure of the transducer is designed.The shock wave initiated by the explosive-driven flyer is numerically calculated.The discharge characteristics of the ferroelectric ceramic transducer are simulated.Simulation in MATLAB demonstrates that the power level of the ferroelectric ceramic transducer could reach up to megawatt.In the case of short-circuit load,current waveform is approximately square wave.Meanwhile,small inductive and resistive composite load resents the damping oscillation waveform.
