| Abstract: | Based on the wave equation and the frequency equation,the analytical model of piezoelectric ceramic actuator for ultrasonic vibration cutting with electroplated diamond wire saw was established,and the structure sizes of the various components of piezoelectric ceramic actuator were gained. By using the ANSYS software,the dynamic analysis and optimum design of piezoelectric ceramic actuator were accomplished,the optimum model of piezoelectric ceramic actuator was achieved.The analysis results showed that the finite element method was a useful method to our design and analysis and the transducer had great properties and would be of significant meanings to the following application. |
