| Abstract: | Based on thr requrements of the dynamic characteristics of the piezoelectric actuator and ultrasound modulated electric machining system to the transducer, the piezoelectric ceramic transducer is designed. ANSYS tool is used to establish the model of the piezoelectric crystal, and dynamics characteristics of the piezoelectric crystal are analyzed. By using the ANSYS parametric optimization design method and the multi physical field coupling module, the interaction relationship among the piezoelectric ceramic crystal stack number, the input voltage signal size, output amplitude of vibration displacement and the natural frequency of the crystal pile is analyzed. It is shown that the piezoelectric transducer design is rational and the characteristics analysis is correct. |
