(Color online) Dielectric elastomer actuator. Undeformed dimensions (dashed line): and deformed dimensions under electric potential : . The coordinate systems (X, Y, Z) for the reference configuration and (x, y, z) for the actual configuration overlap with each other, with the origins at the center of the setup.
(Color online) DEA performance under constant nominal electric field kV/mm, 18.0 kV/mm, and 12.0 kV/mm, respectively. (a) Vibration. (b) Comparison between the vibration amplitude and the quasi-static compression.
(Color online) Below and above the frequency range from 340 Hz and 405 Hz in which dynamic blow-up appears, the system oscillates stably. The oscillation (a) and the phase diagram (b) are for the frequency 335 Hz. The oscillation (c) and the phase diagram (d) are for the frequency 410 Hz.
(Color online) Poincaré map for the oscillation under harmonic excitation with frequency (a) 335 Hz, (b) 400 Hz, (c) 410 Hz, and (d) 430 Hz, respectively.
(Color online) Oscillation with damping effects. (a) A damping of leads to constant vibration, under excitation of frequency 410 Hz. (b) Frequency dependence of the amplitude of the constant vibration induced by the damping of .
