Kurzfassung:
Viscoelasticity and charge leakage are two typical dissipations of a dielectric elastomer (DE). During applied voltage loading, the electrodes tune the electromechanical deformation of DE, which results from the non-ideal insulator attribute of the DE. In this article, the influence of the electrodes is considered to establish a thorough electrodes-coupled dissipative model of DE. The effect that electrode thickness and conductivity has on the static and dynamic properties of the DE is investigated, including the electromechanical deformation of DE membrane and the voltage loaded across the thickness direction. It is found that the electromechanical deformation and voltage across the DE membrane gradually reduce with increasing electrode thickness and decreasing electrode conductivity. Resonance characteristics of the DE for varying electrode thickness and conductivity are also analyzed. The results demonstrate that electrodes with minimal thickness and high conductivity mitigate the resonant frequency and enhance the vibration intensity of the DE system.
