Analysis of Motion Stability for Inchworm-Type Piezoelectric Linear Actuator
Abstract
To study the performance of inchworm-type piezoelectric actuator deeply, the structure and working principle of inchworm-type piezoelectric linear actuator are analyzed to study the influence of linear mover to the whole actuator. The clamping stability of the clamping structure is analyzed via experiment. The motion stability of the inchworm-type piezoelectric linear actuator is evaluated by the proposed method which is based on warping ratio of slope and intercept of experiential equation between actuating voltage and corresponding stepping motion displacement. The results show that lost stability ratio is close associated with actuating voltage, and the higher the actuating voltage is, the better stability of stepping displacement the actuator has. The warping ratio of slope and intercept of experiential equation between actuating voltage and corresponding stepping motion displacement is 1.80/0 and 9.070/0 respectively, and it is shown that the actuator has good motion stability.
