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. Coupling motion is obtained by placing this symmetric flexure hinge mechanism with an angle of $\theta =20^\circ $ to the slider. Experimental...
As an effective means of separating the vibration transmitted from rocket to satellite, the Whole-Spacecraft Vibration Isolation (WSVI) has been widely studied and applied in the past 20 years. Based on a new Circular Payload Adapter Fitting (CPAF), this paper studied the vibration principles of the CPAF and established corresponding vibration isolation model. With the piezoelectric stack actuators,...
