In this study, we analyzed dynamic characteristics of a dielectric elastomer actuator (DEA) with pre-stretch by applying water pressure to realize controlling displacement. This experimental system is able to stretch elastomer in an out-of-plane direction. Thus, this experimental system can be applied to driving three-dimensional (3D) shape DEAs. Also, by controlling displacements of 3D shape DEAs, they can be applied to organ models or tactile presentation devices. In order to control displacements of these DEAs, it is necessary to analyze dynamic characteristics of this experimental system. In this paper, we constructed a physical model of this system to analyze dynamic characteristics and compared experimental values of the displacement and frequency response with theoretical values.
