چکیده
A novel pure rotary actuator with a double-layer flexible mechanism (RA-DFM), which is driven by single piezoelectric ceramic in the lower and generates rotational motion upper mechanism, proposed this paper. The output of successively amplified using an enhanced double Scott–Russell two lever-type mechanisms to obtain large rotation range. static, kinematic dynamic properties RA-DFM are numerically analyzed, actual analyzed considering input stiffness. geometric parameters optimized based on constructed numerical models. Finite element analysis has been implemented validate correctness theoretical models further evaluate property. simulation results show maximal angle 15.14 mrad 0.44% center drift.

Design, Prototyping, and Characterization of an Innovative Piezoelectric Rotary Actuator
An innovative actuation principle is introduced in this paper to drive a rotary motor using an anisotropic piezoelectric composite laminate. The driving element is a three layer laminated beam with piezoceramics sandwiched between two anti-symmetric composite laminae. By taking advantage of material anisotropy, torsional motion can be induced from in-plane strain actuation. With such structural...

متن کاملDesign and Fabrication of an Array Microejector Driven by a Shear-Mode Piezoelectric Actuator
This paper reports a novel actuating design that uses the shear deformation of a piezoelectric actuator to deflect a bulge-diaphragm for driving an array microdroplet ejector. In essence, we employed a circular-shaped actuator poled radial direction with remnant polarization normal to the actuating electric field for inducing the piezoelectric shear effect. The array microdroplet ejector consis...
