摘要：

A piezoelectric-driven actuator based on coupling motion has been proposed and tested to achieve a large linear working stroke with high resolution. "Z-shaped" flexure hinges are exploited for the symmetric flexure hinge mechanism to reduce the structural stress. Couplingmotion is obtained by placing this symmetric flexure hinge mechanism with an angle of theta = 20 degrees to the slider. Experimental results indicate that linear motion with a large working stroke is effectively obtained by this coupling motion; the maximum motion speed is V-s = 6057 mu m/s and the maximumoutput force is F-g = 350 g. Additionally, the influences of input frequency f and input voltage U-e are investigated, and the system kinetic model is established to better analyze the performance of this designed piezoelectric-driven linear actuator.
