A design methodology is presented, which makes it possible to optimize conically-shaped dielectric-elastomer (DE) linear actuators for known active material and required stiffness to an external load. The actuators are obtained by coupling DE films with compliant mechanisms that suitably modify the force generated by the elastomer films. The electromechanical properties of the DE films are determined through finite element analysis. The sizing of the compliant mechanisms is obtained through pseudo-rigid-body models and subsequently verified through finite element analysis. Experimental validation show that the designed actuators work as desired.

Abstract

A design methodology is presented, which makes it possible to optimize conically-shaped dielectric-elastomer (DE) linear actuators for known active material and required stiffness to an external load. The actuators are obtained by coupling DE films with compliant mechanisms that suitably modify the force generated by the elastomer films. The electromechanical properties of the DE films are determined through finite element analysis. The sizing of the compliant mechanisms is obtained through pseudo-rigid-body models and subsequently verified through finite element analysis. Experimental validation show that the designed actuators work as desired.
