Paper Abstract

An innovative actuation principle is introduced in this paper to make a rotary actuator. The driving element is a three layer laminated beam with piezoceramics sandwiched between two anti-symmetric composite laminae. By taking advantage of material anisotropy, a torsional motion can be induced from in-plane strain actuation. With this structural coupling, a rotary actuator can be implemented. In addition to conceptual design, a prototype was fabricated. A finite element analysis was performed as well to model the mentioned device. Both experimental observation and computational simulation confirm the proposed actuation principle.
