Dynamic response of dielectric elastomer under electrical loading condition

摘要

The present paper is concerned with the analytical modeling for a dielectric elastomeric actuator under the electrical loading condition. A common usage of a dielectric elastomeric actuator is to realize simultaneous displacements when an electrical loading is applied. These simultaneous displacements are advantageous in the field of robotics and smart manufacturing industries. A fundamental deformation approach is presented to model the dynamic response of a homogeneously deformed dielectric elastomer with the application of electrical loading condition. The dynamic equation of motion is formulated through the standard Euler-Lagrange method. The numerical results obtained from the developed equation of motion are discussed in comparison with the similar results presented in the literature to show the vibration and oscillation behaviour of the dielectric elastomer.
