- Abstract
The axial force difference aroused from applying high DC voltage on the actuator film makes the cylindrical actuator elongate. In order to study the dynamic response of dielectric elastomer cylindrical actuator, the principle and the process of electromechanical coupling activation are analyzed. The electromechanical coupling activation process of cylindrical actuator is similar to creep. A general linear viscoelastic Voigt model is put forward to describe the process and the principal reasons for the error between calculated result and experimental one are discussed. The model is modified according to the non-linear quasitatic displacement and the axial stress change of actuator during its actuation process. Experiment results show that the modified general Voigt model is suitable to characterize the electromechanical coupling process of cylindrical actuator within the working voltage range. Therefore,the presented model can be used for prediction and optimization of the performance of dielectric elastomer cylindrical actuators.
