| Abstract: | The piezoelectric elements were used as electrical-to-mechanical converter to substitute for torque-motor.The driving force was computed and the driving components and magnifying elements of the actuator were selected. The output characteristics of driving force and displacement of the actuator were measured. At the same time, the measurement curves between two parameters are established. |
