Abstract

The dynamic response of a dielectric elastomer actuator with an electrode-elastomer-electrode sandwich structure is modeled and analyzed. The equation of motion is derived by thermodynamic considerations. Due to the exact formulation of the inertia term in three dimensions, the equation of motion involves particularly a quadratic dependence on the first derivative of the deformation. Numerical solutions of the model are presented to show the dynamic response of the DEA, e.g. the vibration under constant electric potential, the oscillation under harmonic electric loadings, and particularly the resonance phenomenon.
