Piezo linear drive mechanism and the rotary drive mechanism piezoelectric

Inertial the analysis of the current status of the piezoelectric actuator based on the proposed piezoelectric bimorph transducer element as the driving force, by controlling the moving mechanism and the support surface between the positive pressure on the friction ordered changes in the formation of directional movement novel piezoelectric drive. Based on this method, the design of the linear piezoelectric drive mcb circuit breaker and the rotary type piezoelectric drive mechanism. Specific studies are as follows: Through the analysis of the characteristics of piezoelectric material, indicating bimorph can be used as the basic element to achieve inertial impaction. Discusses the use of piezoelectric bimorph vibrator  circuit breakers positive pressure changes inertial piezoelectric drive mechanism of the structure and drive mechanism, the kinematic characteristics were analyzed. Analyzed by the finite element software vibrator vibrator structural parameters on the ends of the static deformation and natural frequency; Voltage stabilizer and experimental testing of two analytical methods for the selected bimorph vibrator were static and dynamic characterization. Tested by experiment, select the appropriate sector of the piezoelectric actuator drive power signal; analyzes the drive supply voltage, operating frequency, and the speed and load on the body of step rule, proposed control method.
